How Did Our Universe Get Here?—The Controversy
ASTRONAUTS thrill to photograph the earth as it looms large through the window of a spacecraft. “That’s the best part of flying in space,” said one. But our earth seems very small when compared with the solar system. The sun could hold a million earths inside, with room to spare! However, could such facts about the universe have any bearing on your life and its meaning?
Let us take a brief mental trip into space to see our earth and sun in perspective. Our sun is just one of an awesome number of stars in a spiral arm of the Milky Way galaxy,a which itself is just a tiny part of the universe. With the naked eye, it is possible to see a few smudges of light that actually are other galaxies, such as the beautiful and larger Andromeda. The Milky Way, Andromeda, and some 20 other galaxies are bound gravitationally into a cluster, all of these being only a small neighborhood in a vast supercluster. The universe contains countless superclusters, and the picture does not end there.
The clusters are not evenly distributed in space. On a grand scale, they look like thin sheets and filaments around vast bubblelike voids. Some features are so long and wide that they resemble great walls. This may surprise many who think that our universe created itself in a chance cosmic explosion. “The more clearly we can see the universe in all its glorious detail,” concludes a senior writer for Scientific American, “the more difficult it will be for us to explain with a simple theory how it came to be that way.”
Evidence Pointing to a Beginning
All the individual stars you see are in the Milky Way galaxy. Until the 1920’s, that seemed to be the only galaxy. You probably know, though, that observations with larger telescopes have since proved otherwise. Our universe contains at least 50,000,000,000 galaxies. We do not mean 50 billion stars—but at least 50 billion galaxies, each with billions of stars like our sun. Yet it was not the staggering quantity of huge galaxies that shook scientific beliefs in the 1920’s. It was that they are all in motion.
Astronomers discovered a remarkable fact: When galactic light was passed through a prism, the light waves were seen to be stretched, indicating motion away from us at great speed. The more distant a galaxy, the faster it appeared to be receding. That points to an expanding universe!b
Even if we are neither professional astronomers nor amateurs, we can see that an expanding universe would have profound implications about our past—and perhaps our personal future too. Something must have started the process—a force powerful enough to overcome the immense gravity of the entire universe. You have good reason to ask, ‘What could be the source of such dynamic energy?’
Although most scientists trace the universe back to a very small, dense beginning (a singularity), we cannot avoid this key issue: “If at some point in the past, the Universe was once close to a singular state of infinitely small size and infinite density, we have to ask what was there before and what was outside the Universe. . . . We have to face the problem of a Beginning.”—Sir Bernard Lovell.
This implies more than just a source of vast energy. Foresight and intelligence are also needed because the rate of expansion seems very finely tuned. “If the Universe had expanded one million millionth part faster,” said Lovell, “then all the material in the Universe would have dispersed by now. . . . And if it had been a million millionth part slower, then gravitational forces would have caused the Universe to collapse within the first thousand million years or so of its existence. Again, there would have been no long-lived stars and no life.”
Attempts to Explain the Beginning
Can experts now explain the origin of the universe? Many scientists, uncomfortable with the idea that the universe was created by a higher intelligence, speculate that by some mechanism it created itself out of nothing. Does that sound reasonable to you? Such speculations usually involve some variation of a theory (inflationary universe model)c conceived in 1979 by physicist Alan Guth. Yet, more recently, Dr. Guth admitted that his theory “does not explain how the universe arose from nothing.” Dr. Andrei Linde was more explicit in a Scientific American article: “Explaining this initial singularity—where and when it all began—still remains the most intractable problem of modern cosmology.”
If experts cannot really explain either the origin or the early development of our universe, should we not look elsewhere for an explanation? Indeed, you have valid reasons to consider some evidence that many have overlooked but that may give you real insight on this issue. The evidence includes the precise measurements of four fundamental forces that are responsible for all properties and changes affecting matter. At the mere mention of fundamental forces, some may hesitate, thinking, ‘That’s solely for physicists.’ Not so. The basic facts are worth considering because they affect us.
Fine-Tuning
The four fundamental forces come into play both in the vastness of the cosmos and in the infinite smallness of atomic structures. Yes, everything we see around us is involved.
Elements vital for our life (particularly carbon, oxygen, and iron) could not exist were it not for the fine-tuning of the four forces evident in the universe. We already mentioned one force, gravity. Another is the electromagnetic force. If it were significantly weaker, electrons would not be held around the nucleus of an atom. ‘Would that be serious?’ some might wonder. Yes, because atoms could not combine to form molecules. Conversely, if this force were much stronger, electrons would be trapped on the nucleus of an atom. There could be no chemical reactions between atoms—meaning no life. Even from this standpoint, it is clear that our existence and life depend on the fine-tuning of the electromagnetic force.
And consider the cosmic scale: A slight difference in the electromagnetic force would affect the sun and thus alter the light reaching the earth, making photosynthesis in plants difficult or impossible. It could also rob water of its unique properties, which are vital for life. So again, the precise tuning of the electromagnetic force determines whether we live or not.
Equally vital is the intensity of the electromagnetic force in relation to the other three. For example, some physicists figure this force to be 10,000,- 000,000,000,000,000,000,000,000,000,000,000,000 (1040) times that of gravity. It might seem a small change to that number to add one more zero (1041). Yet that would mean that gravity is proportionally weaker, and Dr. Reinhard Breuer comments on the resulting situation: “With lower gravity the stars would be smaller, and the pressure of gravity in their interiors would not drive the temperature high enough for nuclear fusion reactions to get under way: the sun would be unable to shine.” You can imagine what that would mean for us!
What if gravity were stronger proportionately, so that the number had only 39 zeros (1039)? “With just this tiny adjustment,” continues Breuer, “a star like the sun would find its life expectancy sharply reduced.” And other scientists consider the fine-tuning to be even more precise.
Indeed, two remarkable qualities of our sun and other stars are long-term efficiency and stability. Consider a simple illustration. We know that to run efficiently, an automobile engine needs a critical ratio between fuel and air; engineers design complex mechanical and computer systems to optimize performance. If that is so with a mere engine, what of the efficiently “burning” stars such as our sun? The key forces involved are precisely tuned, optimized for life. Did that precision just happen? The ancient man Job was asked: “Did you proclaim the rules that govern the heavens, or determine the laws of nature on earth?” (Job 38:33, The New English Bible) No human did. So from where does the precision come?
The Two Nuclear Forces
The structure of the universe involves much more than fine-tuning just gravity and the electromagnetic force. Two other physical forces also relate to our life.
These two forces operate in the nucleus of an atom, and they give ample evidence of forethought. Consider the strong nuclear force, which glues protons and neutrons together in the nucleus of the atom. Because of this bonding, various elements can form—light ones (such as helium and oxygen) and heavy ones (such as gold and lead). It seems that if this binding force were a mere 2-percent weaker, only hydrogen would exist. Conversely, if this force were slightly stronger, only heavier elements, but no hydrogen, could be found. Would our lives be affected? Well, if the universe lacked hydrogen, our sun would not have the fuel it needs to radiate life-giving energy. And, of course, we would have no water or food, since hydrogen is an essential ingredient of both.
The fourth force in this discussion, called the weak nuclear force, controls radioactive decay. It also affects thermonuclear activity in our sun. ‘Is this force fine-tuned?’ you might ask. Mathematician and physicist Freeman Dyson explains: “The weak [force] is millions of times weaker than the nuclear force. It is just weak enough so that the hydrogen in the sun burns at a slow and steady rate. If the weak [force] were much stronger or much weaker, any forms of life dependent on sunlike stars would again be in difficulties.” Yes, this precise rate of burning keeps our earth warm—but not incinerated—and keeps us alive.
Furthermore, scientists believe that the weak force plays a role in supernova explosions, which they give as the mechanism for producing and distributing most elements. “If those nuclear forces were in any way slightly different from the way they actually are, the stars would be incapable of making the elements of which you and I are composed,” explains physicist John Polkinghorne.
More could be said, but you likely understand the point. There is an amazing degree of fine-tuning in these four fundamental forces. “All around us, we seem to see evidence that nature got it just right,” wrote Professor Paul Davies. Yes, the precise tuning of the fundamental forces has made possible the existence and operation of our sun, our delightful planet with its life-sustaining water, our atmosphere so vital for life, and a vast array of precious chemical elements on earth. But ask yourself, ‘Why such precise tuning, and from where?’
Earth’s Ideal Features
Our existence requires precision in other respects as well. Consider the earth’s measurements and its position relative to the rest of our solar system. The Bible book of Job contains these humbling questions: “Where did you happen to be when I founded the earth? . . . Who set its measurements, in case you know?” (Job 38:4, 5) As never before, those questions beg for answers. Why? Because of the amazing things that have been discovered about our earth—including its size and its position in our solar system.
No planet like earth has been found elsewhere in the universe. True, some scientists point to indirect evidence that certain stars have orbiting them objects that are hundreds of times larger than the earth. Our earth, though, is just the right size for our existence. In what sense? If earth were slightly larger, its gravity would be stronger and hydrogen, a light gas, would collect, being unable to escape the earth’s gravity. Thus, the atmosphere would be inhospitable to life. On the other hand, if our earth were slightly smaller, life-sustaining oxygen would escape and surface water would evaporate. In either case, we could not live.
The earth is also at an ideal distance from the sun, a factor vital for life to thrive. Astronomer John Barrow and mathematician Frank Tipler studied “the ratio of the Earth’s radius and distance from the Sun.” They concluded that human life would not exist “were this ratio slightly different from what it is observed to be.” Professor David L. Block notes: “Calculations show that had the earth been situated only 5 per cent closer to the sun, a runaway greenhouse effect [overheating of the earth] would have occurred about 4 000 million years ago. If, on the other hand, the earth were placed only 1 per cent further from the sun, runaway glaciation [huge sheets of ice covering much of the globe] would have occurred some 2 000 million years ago.”—Our Universe: Accident or Design?
To the above precision, you can add the fact that the earth rotates on its axis once a day, the right speed to produce moderate temperatures. Venus takes 243 days to rotate. Just think if the earth took as long! We could not survive the extreme temperatures resulting from such long days and nights.
Another vital detail is our earth’s path around the sun. Comets have a wide elliptic path. Thankfully, this is not so with the earth. Its orbit is almost circular. Again, this prevents us from experiencing death-dealing extremes of temperature.
Nor should we ignore the location of our solar system. Were it nearer the center of the Milky Way galaxy, the gravitational effect of neighboring stars would distort the orbit of the earth. In contrast, were it situated at the very edge of our galaxy, the night sky would be all but devoid of stars. Starlight is not essential to life, but does it not add great beauty to our night sky? And based on current concepts of the universe, scientists have calculated that at the edges of the Milky Way, there would not have been enough of the needed chemical elements to form a solar system like ours.d
Law and Order
From personal experience, you likely know that all things tend toward disorder. As any homeowner has observed, when left to themselves, things tend to break down or disintegrate. Scientists refer to this tendency as “the second law of thermodynamics.” We can see this law at work daily. If left alone, a new automobile or bicycle will become scrap. Abandon a building and it will become a ruin. What about the universe? The law applies there too. So you might think that the order throughout the universe should give way to complete disorder.
However, this does not seem to be happening to the universe, as Professor of Mathematics Roger Penrose discovered when he studied the state of disorderliness (or, entropy) of the observable universe. A logical way to interpret such findings is to conclude that the universe started off in an ordered state and is still highly organized. Astrophysicist Alan Lightman noted that scientists “find it mysterious that the universe was created in such a highly ordered condition.” He added that “any successful theory of cosmology should ultimately explain this entropy problem”—why the universe has not become chaotic.
In fact, our existence is contrary to this recognized law. So why is it that we are alive here on earth? As previously noted, that is a basic question that we should want answered.

a The Milky Way galaxy is some 600 quadrillion miles [about a quintillion km] in diameter—yes, 600,000,000,000,000,000 miles [1,000,000,000,000,000,000 km]! It takes light 100,000 years to cross it, and this one galaxy contains over 100 billion stars!
b In 1995, scientists noticed the strange behavior of the most distant star (SN 1995K) ever observed as it exploded in its galaxy. Like supernovas in nearby galaxies, this star became very bright and then slowly faded but over a longer period than ever before detected. New Scientist magazine plotted this on a graph and explained: “The shape of the light curve . . . is stretched in time by exactly the amount expected if the galaxy was receding from us at nearly half the speed of light.” The conclusion? This is “the best evidence yet that the Universe really is expanding.”
c The inflation theory speculates as to what happened a fraction of a second after the beginning of the universe. Advocates of inflation hold that the universe was initially submicroscopic and then inflated faster than the speed of light, a claim that cannot be tested in a laboratory. Inflation remains a debated theory.
d Scientists have found that the elements reveal amazing order and harmony. Interesting evidence is presented in the Appendix “Architectural Units of the Universe,” page 26.

Trying to Number the Stars
It is estimated that the Milky Way galaxy has more than 100,000,000,000 (100 billion) stars. Picture an encyclopedia devoting one page to each of these stars—our sun and the rest of our solar system would be limited to one page. How many volumes would the set need to have in order to cover the stars in the Milky Way?
With volumes of reasonable thickness, it is said that the encyclopedia would not fit in the New York Public Library, with its 256 miles [412 km] of shelf space!
How long would it take you to examine those pages? “To flip through it, at the rate of a page per second, would require over ten thousand years,” explains Coming of Age in the Milky Way. Yet the stars making up our galaxy are but a small fraction of the stars in the estimated 50,000,000,000 (50 billion) galaxies in the universe. If the encyclopedia contained a page for each of these stars, it would not fit on all the library shelves on earth. “The more we know about the universe,” notes the book, “the more we come to see how little we know.”

Jastrow—On the Beginning
Robert Jastrow, Professor of Astronomy and Geology at Columbia University, wrote: “Few astronomers could have anticipated that this event—the sudden birth of the Universe—would become a proven scientific fact, but observations of the heavens through telescopes have forced them to that conclusion.”
He then commented on the implications: “The astronomical proof of a Beginning places scientists in an awkward position, for they believe that every effect has a natural cause . . . The British astronomer E. A. Milne wrote, ‘We can make no propositions about the state of affairs [in the beginning]; in the Divine act of creation God is unobserved and unwitnessed.’”—The Enchanted Loom—Mind in the Universe.

Four Fundamental Physical Forces
1. Gravity—a very weak force on the level of atoms. It affects large objects—planets, stars, galaxies.
2. Electromagnetism—the key attracting force between protons and electrons, allowing molecules to form. Lightning is one evidence of its power.
3. Strong nuclear force—the force that glues protons and neutrons together in the nucleus of an atom.
4. Weak nuclear force—the force that governs the decay of radioactive elements and the efficient thermonuclear activity of the sun.
[Box on page 20]
“Combination of Coincidences”
“Make the weak force slightly stronger and no helium would have been produced; make it slightly weaker and nearly all the hydrogen would have been converted into helium.”
“The window of opportunity for a universe in which there is some helium and there are also exploding supernovas is very narrow. Our existence depends on this combination of coincidences, and on the even more dramatic coincidence of nuclear energy levels predicted by [astronomer Fred] Hoyle. Unlike all previous generations, we know how we come to be here. But, like all previous generations, we still do not know why.”—New Scientist.
[Box on page 22]
“The special conditions on earth resulting from its ideal size, element composition, and nearly circular orbit at a perfect distance from a long-lived star, the sun, made possible the accumulation of water on the earth’s surface.” (Integrated Principles of Zoology, 7th edition) Life on earth could not have appeared without water.
[Box on page 24]
Believe Only What You See?
Many rational people accept the existence of things they cannot see. In January 1997, Discover magazine reported that astronomers detected what they concluded were about a dozen planets orbiting distant stars.
“So far the new planets are known only from the way their gravity perturbs the motion of the parent stars.” Yes, for the astronomers, the visible effects of gravity constituted a basis for believing in the existence of unseen heavenly bodies.
Related evidence—not direct observation—was an adequate basis for scientists to accept what was yet invisible. Many who believe in a Creator conclude that they have a similar basis for accepting what they cannot see.
[Box on page 25]
Sir Fred Hoyle explains in The Nature of the Universe: “To avoid the issue of creation it would be necessary for all the material of the Universe to be infinitely old, and this it cannot be. . . . Hydrogen is being steadily converted into helium and the other elements . . . How comes it then that the Universe consists almost entirely of hydrogen? If matter were infinitely old this would be quite impossible. So we see that the Universe being what it is, the creation issue simply cannot be dodged.”

Chapter Three
What Is the Origin of Life?
OUR earth teems with life. From the snowy Arctic to the Amazon rain forest, from the Sahara Desert to the Everglades swamp, from the dark ocean floor to bright mountain peaks—life abounds. And it is loaded with the potential to amaze us.
It comes in types, sizes, and quantities that stagger the imagination. A million species of insects hum and wiggle on our planet. In the waters around us swim over 20,000 species of fish—some the size of a grain of rice, others as long as a truck. At least 350,000 plant species—some weird, most wonderful—embellish the land. And over 9,000 species of birds fly overhead. These creatures, including man, form the panorama and symphony that we refer to as life.
But more amazing than the delightful variety around us is the profound unity linking them. Biochemists, who peek beneath the skin of earth’s creatures, explain that all living things—be they amoebas or humans—depend on an awesome interaction: the teamwork between nucleic acids (DNA and RNA) and protein molecules. The intricate processes involving these components occur in virtually all our body cells, as it does in the cells of hummingbirds, lions, and whales. This uniform interaction produces a beautiful mosaic of life. How did this orchestration of life come about? In fact, what is the origin of life?
Likely you accept that at one time the earth had no life on it. Scientific opinion agrees, and so do many religious books. Still, you may realize that those two sources—science and religion—differ in explaining how life began on earth.
Millions of people of all educational levels believe that an intelligent Creator, the original Designer, produced life on earth. In contrast, many scientists say that life arose from nonliving matter, one chemical step after another, merely by chance. Is it one, or is it the other?
We should not think that this issue is rather remote from us and from our finding a more meaningful life. As already noted, one of the very fundamental questions humans have sought to answer is, Where did we as living humans come from?
Most science courses focus on the adaptation and survival of life-forms instead of on the more central question of the very origin of life. You may have noted that attempts to explain where life came from are usually presented in generalizations such as: ‘Over millions of years, molecules in collision somehow produced life.’ Yet, is that really satisfying? It would mean that in the presence of energy from the sun, lightning, or volcanoes, some lifeless matter moved, became organized, and eventually started living—all of this without directed assistance. What a huge leap that would have been! From nonliving matter to living! Could it have occurred that way?
Back in the Middle Ages, accepting such a concept might not have seemed a problem because spontaneous generation—the notion that life could arise spontaneously from nonliving matter—was a prevailing belief. Finally, in the 17th century, Italian physician Francesco Redi proved that maggots appeared in rotten meat only after flies had laid eggs on it. No maggots developed on meat that flies could not reach. If animals as big as flies did not just appear on their own, what about the microbes that kept appearing in food—covered or not? Although later experiments indicated that microbes did not arise spontaneously, the issue remained controversial. Then came the work of Louis Pasteur.
Many people recall Pasteur’s work in solving problems related to fermentation and to infectious disease. He also performed experiments to determine whether tiny life-forms could arise by themselves. As you may have read, Pasteur demonstrated that even minute bacteria did not form in sterilized water protected from contamination. In 1864 he announced: “Never will the doctrine of spontaneous generation recover from the mortal blow struck by this simple experiment.” That statement remains true. No experiment has ever produced life from nonliving matter.
How then could life come to be on earth? Modern efforts to answer that question might be dated to the 1920’s, to the work of Russian biochemist Alexander I. Oparin. He and other scientists since then have offered something like the script of a three-act drama that depicts what is claimed to have occurred on the stage of planet Earth. The first act portrays earth’s elements, or raw materials, being transformed into groups of molecules. Then comes the jump to large molecules. And the last act of this drama presents the leap to the first living cell. But did it really happen that way?
Fundamental to that drama is explaining that earth’s early atmosphere was much different from what it is today. One theory assumes that free oxygen was virtually absent and that the elements nitrogen, hydrogen, and carbon formed ammonia and methane. The concept is that when lightning and ultraviolet light struck an atmosphere of these gases and water vapor, sugars and amino acids developed. Bear in mind, though, that this is theory.
According to this theoretical drama, such molecular forms washed into the oceans or other bodies of water. Over time, sugars, acids, and other compounds concentrated into a broth of “prebiotic soup” where amino acids, for instance, joined to become proteins. Extending this theoretical progression, other compounds called nucleotides formed chains and became a nucleic acid, such as DNA. All of this supposedly set the stage for the final act of the molecular drama.
One might depict this last act, which is undocumented, as a love story. Protein molecules and DNA molecules happen to meet, recognize each other, and embrace. Then, just before the curtain rings down, the first living cell is born. If you were following this drama, you might wonder, ‘Is this real life or fiction? Could life on earth really have originated in this way?’
Genesis in the Laboratory?
In the early 1950’s, scientists set out to test Alexander Oparin’s theory. It was an established fact that life comes only from life, yet scientists theorized that if conditions differed in the past, life might have come slowly from nonlife. Could that be demonstrated? Scientist Stanley L. Miller, working in the laboratory of Harold Urey, took hydrogen, ammonia, methane, and water vapor (assuming that this had been the primitive atmosphere), sealed these in a flask with boiling water at the bottom (to represent an ocean), and zapped electric sparks (like lightning) through the vapors. Within a week, there were traces of reddish goo, which Miller analyzed and found to be rich in amino acids—the essence of proteins. You may well have heard of this experiment because for years it has been cited in science textbooks and school courses as if it explains how life on earth began. But does it?
Actually, the value of Miller’s experiment is seriously questioned today. (See “Classic but Questionable,” pages 36-7.) Nevertheless, its apparent success led to other tests that even produced components found in nucleic acids (DNA or RNA). Specialists in the field (sometimes called origin-of-life scientists) felt optimistic, for they had seemingly replicated the first act of the molecular drama. And it seemed as though laboratory versions of the remaining two acts would follow. One chemistry professor claimed: “The explanation of the origin of a primitive living system by evolutionary mechanisms is well within sight.” And a science writer observed: “Pundits speculated that scientists, like Mary Shelley’s Dr. Frankenstein, would shortly conjure up living organisms in their laboratories and thereby demonstrate in detail how genesis unfolded.” The mystery of the spontaneous origin of life, many thought, was solved.—See “Right Hand, Left Hand,” page 38.
Moods Change—Riddles Remain
In the years since, however, that optimism has evaporated. Decades have passed, and life’s secrets remain elusive. Some 40 years after his experiment, Professor Miller told Scientific American: “The problem of the origin of life has turned out to be much more difficult than I, and most other people, envisioned.” Other scientists share this change of mood. For example, back in 1969, Professor of Biology Dean H. Kenyon coauthored Biochemical Predestination. But more recently he concluded that it is “fundamentally implausible that unassisted matter and energy organized themselves into living systems.”
Indeed, laboratory work bears out Kenyon’s assessment that there is “a fundamental flaw in all current theories of the chemical origins of life.” After Miller and others had synthesized amino acids, scientists set out to make proteins and DNA, both of which are necessary for life on earth. After thousands of experiments with so-called prebiotic conditions, what was the outcome? The Mystery of Life’s Origin: Reassessing Current Theories notes: “There is an impressive contrast between the considerable success in synthesizing amino acids and the consistent failure to synthesize protein and DNA.” The latter efforts are characterized by “uniform failure.”
Realistically, the mystery encompasses more than how the first protein and nucleic acid (DNA or RNA) molecules came into existence. It includes how they work together. “It is only the partnership of the two molecules that makes contemporary life on Earth possible,” says The New Encyclopædia Britannica. Yet the encyclopedia notes that how that partnership could come about remains “a critical and unsolved problem in the origin of life.” True, indeed.
Appendix A, “Teamwork for Life” (pages 45-7), reviews some basic details of the intriguing teamwork between protein and nucleic acids in our cells. Even such a glimpse into the realm of our body cells elicits admiration for the work of scientists in this field. They have shed light on extraordinarily complex processes that few of us even think about but that operate every moment of our lives. From another standpoint, however, the staggering complexity and precision required returns us to the question, How did all of this come about?
You may know that origin-of-life scientists have not ceased trying to formulate a plausible scenario for the drama about the first appearance of life. Nevertheless, their new scripts are not proving to be convincing. (See Appendix B, “From ‘the RNA World’ or Another World?” page 48.) For example, Klaus Dose of the Institute for Biochemistry in Mainz, Germany, observed: “At present all discussions on principal theories and experiments in the field either end in stalemate or in a confession of ignorance.”
Even at the 1996 International Conference on the Origin of Life, no solutions were forthcoming. Instead, the journal Science reported that the nearly 300 scientists who convened had “grappled with the riddle of how [DNA and RNA] molecules first appeared and how they evolved into self-reproducing cells.”
Intelligence and advanced education were required to study and even begin to explain what occurs at the molecular level in our cells. Is it reasonable to believe that complicated steps occurred first in a “prebiotic soup,” undirected, spontaneously, and by chance? Or was more involved?
Why the Riddles?
A person today can look back over nearly half a century of speculation and thousands of attempts to prove that life originated on its own. If one does that, it would be hard to disagree with Nobel laureate Francis Crick. Speaking about origin-of-life theories, Crick observed that there is “too much speculation running after too few facts.” It is thus understandable that some scientists who examine the facts conclude that life is much too complex to pop up even in an organized laboratory, let alone in an uncontrolled environment.
If advanced science cannot prove that life could arise by itself, why do some scientists continue to hold to such theories? A few decades ago, Professor J. D. Bernal offered some insight in the book The Origin of Life: “By applying the strict canons of scientific method to this subject [the spontaneous generation of life], it is possible to demonstrate effectively at several places in the story, how life could not have arisen; the improbabilities are too great, the chances of the emergence of life too small.” He added: “Regrettably from this point of view, life is here on Earth in all its multiplicity of forms and activities and the arguments have to be bent round to support its existence.” And the picture has not improved.
Consider the underlying import of such reasoning. It is as much as saying: ‘Scientifically it is correct to state that life cannot have begun by itself. But spontaneously arising life is the only possibility that we will consider. So it is necessary to bend the arguments to support the hypothesis that life arose spontaneously.’ Are you comfortable with such logic? Does not such reasoning call for a lot of ‘bending’ of the facts?
There are, however, knowledgeable, respected scientists who do not see a need to bend facts to fit a prevailing philosophy on the origin of life. Rather, they permit the facts to point to a reasonable conclusion. What facts and what conclusion?
Information and Intelligence
Interviewed in a documentary film, Professor Maciej Giertych, a noted geneticist from the Institute of Dendrology of the Polish Academy of Sciences, answered:
“We have become aware of the massive information contained in the genes. There is no known way to science how that information can arise spontaneously. It requires an intelligence; it cannot arise from chance events. Just mixing letters does not produce words.” He added: “For example, the very complex DNA, RNA, protein replicating system in the cell must have been perfect from the very start. If not, life systems could not exist. The only logical explanation is that this vast quantity of information came from an intelligence.”
The more you learn about the wonders of life, the more logical it is to agree with that conclusion: The origin of life requires an intelligent source. What source?
As noted earlier, millions of educated individuals conclude that life on earth must have been produced by a higher intelligence, a designer. Yes, after examining the matter fairly, they have accepted that even in our scientific age, it is reasonable to agree with the Biblical poet who long ago said about God: “For with you is the source of life.”—Psalm 36:9.
Whether you have yet reached a firm conclusion about that or not, let us turn our attention to some wonders that involve you personally. Doing so is most satisfying and may shed considerable light on this matter that touches our lives.
[Box on page 30]
How Much Chance for Chance?
“Chance, and chance alone, did it all, from the primeval soup to man,” said Nobel laureate Christian de Duve, speaking about the origin of life. Is chance, though, a rational explanation for the cause of life?
What is chance? Some think in terms of a mathematical probability, such as the chance involved in flipping a coin. However, that is not how many scientists use “chance” regarding the origin of life. The vague word “chance” is used as a substitute for a more precise word such as “cause,” especially when the cause is not known.
“To personify ‘chance’ as if we were talking about a causal agent,” notes biophysicist Donald M. MacKay, “is to make an illegitimate switch from a scientific to a quasi-religious mythological concept.” Similarly, Robert C. Sproul points out: “By calling the unknown cause ‘chance’ for so long, people begin to forget that a substitution was made. . . . The assumption that ‘chance equals an unknown cause’ has come to mean for many that ‘chance equals cause.’”
Nobel laureate Jacques L. Monod, for one, used this chance-equals-cause line of reasoning. “Pure chance, absolutely free but blind, [is] at the very root of the stupendous edifice of evolution,” he wrote. “Man knows at last that he is alone in the universe’s unfeeling immensity, out of which he emerged only by chance.” Note he says: ‘BY chance.’ Monod does what many others do—he elevates chance to a creative principle. Chance is offered as the means by which life came to be on earth.
In fact, dictionaries show that “chance” is “the assumed impersonal purposeless determiner of unaccountable happenings.” Thus, if one speaks about life coming about by chance, he is saying that it came about by a causal power that is not known. Could it be that some are virtually spelling “Chance” with a capital letter—in effect saying, Creator?

“[The smallest bacterium] is so much more like people than Stanley Miller’s mixtures of chemicals, because it already has these system properties. So to go from a bacterium to people is less of a step than to go from a mixture of amino acids to that bacterium.”—Professor of Biology Lynn Margulis
[Box/Picture on page 36, 37]
Classic but Questionable
Stanley Miller’s experiment in 1953 is often cited as evidence that spontaneous generation could have happened in the past. The validity of his explanation, however, rests on the presumption that the earth’s primordial atmosphere was “reducing.” That means it contained only the smallest amount of free (chemically uncombined) oxygen. Why?
The Mystery of Life’s Origin: Reassessing Current Theories points out that if much free oxygen was present, ‘none of the amino acids could even be formed, and if by some chance they were, they would decompose quickly.’a How solid was Miller’s presumption about the so-called primitive atmosphere?
In a classic paper published two years after his experiment, Miller wrote: “These ideas are of course speculation, for we do not know that the Earth had a reducing atmosphere when it was formed. . . . No direct evidence has yet been found.”—Journal of the American Chemical Society, May 12, 1955.
Was evidence ever found? Some 25 years later, science writer Robert C. Cowen reported: “Scientists are having to rethink some of their assumptions. . . . Little evidence has emerged to support the notion of a hydrogen-rich, highly reducing atmosphere, but some evidence speaks against it.”—Technology Review, April 1981.
And since then? In 1991, John Horgan wrote in Scientific American: “Over the past decade or so, doubts have grown about Urey and Miller’s assumptions regarding the atmosphere. Laboratory experiments and computerized reconstructions of the atmosphere . . . suggest that ultraviolet radiation from the sun, which today is blocked by atmospheric ozone, would have destroyed hydrogen-based molecules in the atmosphere. . . . Such an atmosphere [carbon dioxide and nitrogen] would not have been conducive to the synthesis of amino acids and other precursors of life.”
Why, then, do many still hold that earth’s early atmosphere was reducing, containing little oxygen? In Molecular Evolution and the Origin of Life, Sidney W. Fox and Klaus Dose answer: The atmosphere must have lacked oxygen because, for one thing, “laboratory experiments show that chemical evolution . . . would be largely inhibited by oxygen” and because compounds such as amino acids “are not stable over geological times in the presence of oxygen.”
Is this not circular reasoning? The early atmosphere was a reducing one, it is said, because spontaneous generation of life could otherwise not have taken place. But there actually is no assurance that it was reducing.
There is another telling detail: If the gas mixture represents the atmosphere, the electric spark mimics lightning, and boiling water stands in for the sea, what or who does the scientist arranging and carrying out of the experiment represent?
[Footnote]
a Oxygen is highly reactive. For example, it combines with iron and forms rust or with hydrogen and forms water. If there was much free oxygen in an atmosphere when amino acids were assembling, it would quickly combine with and dismantle the organic molecules as they formed.

Right Hand, Left Hand
We know that there are right-handed and left-handed gloves. This is also true of amino acid molecules. Of some 100 known amino acids, only 20 are used in proteins, and all are left-handed ones. When scientists make amino acids in laboratories, in imitation of what they feel possibly occurred in a prebiotic soup, they find an equal number of right-handed and left-handed molecules. “This kind of 50-50 distribution,” reports The New York Times, is “not characteristic of life, which depends on left-handed amino acids alone.” Why living organisms are made up of only left-handed amino acids is “a great mystery.” Even amino acids found in meteorites “showed excesses of left-handed forms.” Dr. Jeffrey L. Bada, who studies problems involving the origin of life, said that “some influence outside the earth might have played some role in determining the handedness of biological amino acids.”

“A Deliberate Intellectual Act”
British astronomer Sir Fred Hoyle has spent decades studying the universe and life in it, even espousing that life on earth arrived from outer space. Lecturing at the California Institute of Technology, he discussed the order of amino acids in proteins.
“The big problem in biology,” Hoyle said, “isn’t so much the rather crude fact that a protein consists of a chain of amino acids linked together in a certain way, but that the explicit ordering of the amino acids endows the chain with remarkable properties . . . If amino acids were linked at random, there would be a vast number of arrangements that would be useless in serving the purposes of a living cell. When you consider that a typical enzyme has a chain of perhaps 200 links and that there are 20 possibilities for each link, it’s easy to see that the number of useless arrangements is enormous, more than the number of atoms in all the galaxies visible in the largest telescopes. This is for one enzyme, and there are upwards of 2000 of them, mainly serving very different purposes. So how did the situation get to where we find it to be?”
Hoyle added: “Rather than accept the fantastically small probability of life having arisen through the blind forces of nature, it seemed better to suppose that the origin of life was a deliberate intellectual act.”
[Box on page 44]
Professor Michael J. Behe stated: “To a person who does not feel obliged to restrict his search to unintelligent causes, the straightforward conclusion is that many biochemical systems were designed. They were designed not by the laws of nature, not by chance and necessity; rather, they were planned. . . . Life on earth at its most fundamental level, in its most critical components, is the product of intelligent activity.”

Chapter Four
How Unique You Are!
BEFORE starting your activities each morning, do you glance in a mirror to check your appearance? You may not have time to be contemplative then. But take a moment now to marvel at what is involved as you take such a simple glance.
Your eyes enable you to view yourself in full color, even though color vision is not vital to life. The position of your ears gives you stereophonic hearing; thus you can locate the source of sounds, such as the voice of a loved one. We may take that for granted, yet a book for sound engineers comments: “In considering the human hearing system in any depth, however, it is difficult to escape the conclusion that its intricate functions and structures indicate some beneficent hand in its design.”
Your nose also manifests marvelous design. Through it you can breathe air, which keeps you alive. Also, it has millions of sense receptors, enabling you to discern some 10,000 nuances of smell. As you enjoy a meal, another sense comes into play. Thousands of taste buds convey flavors to you. Other receptors on your tongue help you to feel if your teeth are clean.
Yes, you have five senses—sight, hearing, smell, taste, and touch. Granted, some animals have keener night vision, more sensitive smell, or more acute hearing, but man’s balance of these senses certainly allows him to excel in many ways.
Let us, though, consider why we can benefit from these abilities and capacities. All of them depend on the three-pound [1.4 kg] organ inside our head—our brain. Animals have functioning brains. Still, the human brain is in a class by itself, making us undeniably unique. How so? And how does this uniqueness relate to our interest in having a meaningful, lasting life?
Your Marvelous Brain
For years man’s brain has been likened to a computer, yet recent discoveries show that the comparison falls far short. “How does one begin to comprehend the functioning of an organ with somewhere in the neighborhood of 50 billion neurons with a million billion synapses (connections), and with an overall firing rate of perhaps 10 million billion times per second?” asked Dr. Richard M. Restak. His answer? “The performance of even the most advanced of the neural-network computers . . . has about one ten-thousandth the mental capacity of a housefly.” Consider, then, how much a computer fails to measure up to a human brain, which is so remarkably superior.
What man-made computer can repair itself, rewrite its program, or improve over the years? When a computer system needs to be adjusted, a programmer must write and enter new coded instructions. Our brain does such work automatically, both in the early years of life and in old age. You would not be exaggerating to say that the most advanced computers are very primitive compared to the brain. Scientists have called it “the most complicated structure known” and “the most complex object in the universe.” Consider some discoveries that have led many to conclude that the human brain is the product of a caring Creator.
Use It or Lose It
Useful inventions such as cars and jet planes are basically limited by the fixed mechanisms and electrical systems that men design and install. By contrast, our brain is, at the very least, a highly flexible biological mechanism or system. It can keep changing according to the way it is used—or abused. Two main factors seem responsible for how our brain develops throughout our lifetime—what we allow to enter it through our senses and what we choose to think about.
Although hereditary factors may have a role in mental performance, modern research shows that our brain is not fixed by our genes at the time of conception. “No one suspected that the brain was as changeable as science now knows it to be,” writes Pulitzer prize-winning author Ronald Kotulak. After interviewing more than 300 researchers, he concluded: “The brain is not a static organ; it is a constantly changing mass of cell connections that are deeply affected by experience.”—Inside the Brain.
Still, our experiences are not the only means of shaping our brain. It is affected also by our thinking. Scientists find that the brains of people who remain mentally active have up to 40 percent more connections (synapses) between nerve cells (neurons) than do the brains of the mentally lazy. Neuroscientists conclude: You have to use it or you lose it. What, though, of the elderly? There seems to be some loss of brain cells as a person ages, and advanced age can bring memory loss. Yet the difference is much less than was once believed. A National Geographic report on the human brain said: “Older people . . . retain capacity to generate new connections and to keep old ones via mental activity.”
Recent findings about our brain’s flexibility accord with advice found in the Bible. That book of wisdom urges readers to be ‘transformed by making their mind over’ or to be “made new” through “accurate knowledge” taken into the mind. (Romans 12:2; Colossians 3:10) Jehovah’s Witnesses have seen this happen as people study the Bible and apply its counsel. Many thousands—from the whole spectrum of social and educational backgrounds—have done so. They remain distinct individuals, but they have become happier and more balanced, displaying what a first-century writer called “soundness of mind.” (Acts 26:24, 25) Improvements like these result largely from one’s making good use of a part of the cerebral cortex located in the front of the head.
Your Frontal Lobe
Most neurons in the outer layer of the brain, the cerebral cortex, are not linked directly to muscles and sensory organs. For example, consider the billions of neurons that make up the frontal lobe. (See drawing, page 56.) Brain scans prove that the frontal lobe becomes active when you think of a word or call up memories. The front part of the brain plays a special role in your being you.
“The prefrontal cortex . . . is most involved with elaboration of thought, intelligence, motivation, and personality. It associates experiences necessary for the production of abstract ideas, judgment, persistence, planning, concern for others, and conscience. . . . It is the elaboration of this region that sets human beings apart from other animals.” (Marieb’s Human Anatomy and Physiology) We certainly see evidence of this distinction in what humans have accomplished in fields such as mathematics, philosophy, and justice, which primarily involve the prefrontal cortex.
Why do humans have a large, flexible prefrontal cortex, which contributes to higher mental functions, whereas in animals this area is rudimentary or nonexistent? The contrast is so great that biologists who claim that we evolved speak of the “mysterious explosion in brain size.” Professor of Biology Richard F. Thompson, noting the extraordinary expansion of our cerebral cortex, admits: “As yet we have no very clear understanding of why this happened.” Could the reason lie in man’s having been created with this peerless brain capacity?
Unequaled Communication Skills
Other parts of the brain also contribute to our uniqueness. Behind our prefrontal cortex is a strip stretching across the head—the motor cortex. It contains billions of neurons that connect with our muscles. It too has features that contribute to our being far different from apes or other animals. The primary motor cortex gives us “(1) an exceptional capability to use the hand, the fingers, and the thumb to perform highly dexterous manual tasks, and (2) use of the mouth, lips, tongue, and facial muscles to talk.”—Guyton’s Textbook of Medical Physiology.
Consider briefly how the motor cortex affects your ability to speak. Over half of it is devoted to the organs of communication. This helps to explain the unparalleled communication skills of humans. Though our hands play a role in communication (in writing, normal gestures, or sign language), the mouth usually plays the major part. Human speech—from a baby’s first word to the voice of an elderly person—is unquestionably a marvel. Some 100 muscles in the tongue, lips, jaw, throat, and chest cooperate to produce countless sounds. Note this contrast: One brain cell can direct 2,000 fibers of an athlete’s calf muscle, but brain cells for the voice box may concentrate on only 2 or 3 muscle fibers. Does that not suggest that our brain is specially equipped for communication?
Each short phrase that you utter requires a specific pattern of muscular movements. The meaning of a single expression can change depending upon the degree of movement and split-second timing of scores of different muscles. “At a comfortable rate,” explains speech expert Dr. William H. Perkins, “we utter about 14 sounds per second. That’s twice as fast as we can control our tongue, lips, jaw or any other parts of our speech mechanism when we move them separately. But put them all together for speech and they work the way fingers of expert typists and concert pianists do. Their movements overlap in a symphony of exquisite timing.”
The actual information needed to ask the simple question, “How are you today?” is stored in a part of your brain’s frontal lobe called Broca’s area, which some consider to be your speech center. Nobel laureate neuroscientist Sir John Eccles wrote: “No area corresponding to the . . . speech area of Broca has been recognized in apes.” Even if some similar areas are found in animals, the fact is that scientists cannot get apes to produce more than a few crude speech sounds. You, though, can produce complicated language. To do so, you put words together according to the grammar of your language. Broca’s area helps you do that, both in speaking and in writing.
Of course, you cannot exercise the miracle of speech unless you know at least one language and understand what its words mean. This involves another special part of your brain, known as Wernicke’s area. Here, billions of neurons discern the meaning of spoken or written words. Wernicke’s area helps you to make sense of statements and to comprehend what you hear or read; thus you can learn information and can respond sensibly.
There is even more to your fluent speech. To illustrate: A verbal “Hello” can convey a host of meanings. Your tone of voice reflects whether you are happy, excited, bored, rushed, annoyed, sad, or frightened, and it may even reveal degrees of those emotional states. Another area of your brain supplies information for the emotional part of speech. So, various parts of your brain come into play when you communicate.
Chimpanzees have been taught some limited sign language, but their use of it is essentially limited to simple requests for food or other basics. Having worked to teach chimps simple nonverbal communication, Dr. David Premack concluded: “Human language is an embarrassment for evolutionary theory because it is vastly more powerful than one can account for.”
We might ponder: ‘Why do humans have this marvelous skill to communicate thoughts and feelings, to inquire and to respond?’ The Encyclopedia of Language and Linguistics states that “[human] speech is special” and admits that “the search for precursors in animal communication does not help much in bridging the enormous gap that separates language and speech from nonhuman behaviors.” Professor Ludwig Koehler summarized the difference: “Human speech is a secret; it is a divine gift, a miracle.”
What a difference there is between an ape’s use of signs and the complex language ability of children! Sir John Eccles referred to what most of us have also observed, an ability “exhibited even by 3-year-old children with their torrent of questions in their desire to understand their world.” He added: “By contrast, apes do not ask questions.” Yes, only humans form questions, including questions about the meaning of life.
Memory and More!
When you glance in a mirror, you may think of how you looked when you were younger, even comparing that with what your appearance could be in the years to come or how you would look after applying cosmetics. These thoughts can arise almost unconsciously, yet something very special is occurring, something that no animal can experience.
Unlike animals, who mainly live and act on present needs, humans can contemplate the past and plan for the future. A key to your doing that is the brain’s almost limitless memory capacity. True, animals have a degree of memory, and thus they can find their way back home or recall where food may be. Human memory is far greater. One scientist estimated that our brain can hold information that “would fill some twenty million volumes, as many as in the world’s largest libraries.” Some neuroscientists estimate that during an average life span, a person uses only 1/100 of 1 percent (.0001) of his potential brain capacity. You might well ask, ‘Why do we have a brain with so much capacity that we hardly test a fraction of it in a normal lifetime?’
Nor is our brain just some vast storage place for information, like a supercomputer. Biology professors Robert Ornstein and Richard F. Thompson wrote: “The ability of the human mind to learn—to store and recall information—is the most remarkable phenomenon in the biological universe. Everything that makes us human—language, thought, knowledge, culture—is the result of this extraordinary capability.”
Moreover, you have a conscious mind. That statement may seem basic, but it sums up something that unquestionably makes you exceptional. The mind has been described as “the elusive entity where intelligence, decision making, perception, awareness and sense of self reside.” As creeks, streams, and rivers feed into a sea, so memories, thoughts, images, sounds, and feelings flow constantly into or through our mind. Consciousness, says one definition, is “the perception of what passes in a man’s own mind.”
Modern researchers have made great strides in understanding the physical makeup of the brain and some of the electrochemical processes that occur in it. They can also explain the circuitry and functioning of an advanced computer. However, there is a vast difference between brain and computer. With your brain you are conscious and are aware of your being, but a computer certainly is not. Why the difference?
Frankly, how and why consciousness arises from physical processes in our brain is a mystery. “I don’t see how any science can explain that,” one neurobiologist commented. Also, Professor James Trefil observed: “What, exactly, it means for a human being to be conscious . . . is the only major question in the sciences that we don’t even know how to ask.” One reason why is that scientists are using the brain to try to understand the brain. And just studying the physiology of the brain may not be enough. Consciousness is “one of the most profound mysteries of existence,” observed Dr. David Chalmers, “but knowledge of the brain alone may not get [scientists] to the bottom of it.”
Nonetheless, each of us experiences consciousness. For example, our vivid memories of past events are not mere stored facts, like computer bits of information. We can reflect on our experiences, draw lessons from them, and use them to shape our future. We are able to consider several future scenarios and evaluate the possible effects of each. We have the capacity to analyze, create, appreciate, and love. We can enjoy pleasant conversations about the past, present, and future. We have ethical values about behavior and can use them in making decisions that may or may not be of immediate benefit. We are attracted to beauty in art and morals. In our mind we can mold and refine our ideas and guess how other people will react if we carry these out.
Such factors produce an awareness that sets humans apart from other life-forms on earth. A dog, a cat, or a bird looks in a mirror and responds as if seeing another of its kind. But when you look in a mirror, you are conscious of yourself as a being with the capacities just mentioned. You can reflect on dilemmas, such as: ‘Why do some turtles live 150 years and some trees live over 1,000 years, but an intelligent human makes the news if he reaches 100?’ Dr. Richard Restak states: “The human brain, and the human brain alone, has the capacity to step back, survey its own operation, and thus achieve some degree of transcendence. Indeed, our capacity for rewriting our own script and redefining ourselves in the world is what distinguishes us from all other creatures in the world.”
Man’s consciousness baffles some. The book Life Ascending, while favoring a mere biological explanation, admits: “When we ask how a process [evolution] that resembles a game of chance, with dreadful penalties for the losers, could have generated such qualities as love of beauty and truth, compassion, freedom, and, above all, the expansiveness of the human spirit, we are perplexed. The more we ponder our spiritual resources, the more our wonder deepens.” Very true. Thus, we might round out our view of human uniqueness by a few evidences of our consciousness that illustrate why many are convinced that there must be an intelligent Designer, a Creator, who cares for us.
Art and Beauty
“Why do people pursue art so passionately?” asked Professor Michael Leyton in Symmetry, Causality, Mind. As he pointed out, some might say that mental activity such as mathematics confers clear benefits to humans, but why art? Leyton illustrated his point by saying that people travel great distances to art exhibits and concerts. What inner sense is involved? Similarly, people around the globe put attractive pictures or paintings on the walls of their home or office. Or consider music. Most people like to listen to some style of music at home and in their cars. Why? It certainly is not because music once contributed to the survival of the fittest. Says Leyton: “Art is perhaps the most inexplicable phenomenon of the human species.”
Still, we all know that enjoying art and beauty is part of what makes us feel “human.” An animal might sit on a hill and look at a colorful sky, but is it drawn to beauty as such? We look at a mountain torrent shimmering in the sunshine, stare at the dazzling diversity in a tropical rain forest, gaze at a palm-lined beach, or admire the stars sprinkled across the black velvety sky. Often we feel awed, do we not? Beauty of that sort makes our hearts glow, our spirits soar. Why?
Why do we have an innate craving for things that, in reality, contribute little materially to our survival? From where do our aesthetic values come? If we do not take into account a Maker who shaped these values at man’s creation, these questions lack satisfying answers. This is also true regarding beauty in morals.
Moral Values
Many recognize the highest form of beauty to be fine deeds. For instance, being loyal to principles in the face of persecution, acting unselfishly to relieve others’ suffering, and forgiving someone who hurt us are actions that appeal to the moral sense of thinking people everywhere. This is the kind of beauty mentioned in the ancient Biblical proverb: “The insight of a man certainly slows down his anger, and it is beauty on his part to pass over transgression.” Or as another proverb observes: “The desirable thing in earthling man is his loving-kindness.”—Proverbs 19:11, 22.
We all know that some people, and even groups, ignore or trample on elevated morals, but the majority do not. From what source do the moral values found in virtually all areas and in all periods come? If there is no Source of morality, no Creator, did right and wrong simply originate with people, human society? Consider an example: Most individuals and groups hold murder to be wrong. But one could ask, ‘Wrong in comparison to what?’ Obviously there is some sense of morality that underlies human society in general and that has been incorporated into the laws of many lands. What is the source of this standard of morality? Could it not be an intelligent Creator who has moral values and who placed the faculty of conscience, or ethical sense, in humans?—Compare Romans 2:14, 15.
You Can Contemplate the Future and Plan for It
Another facet of human consciousness is our ability to consider the future. When asked whether humans have traits that distinguish them from animals, Professor Richard Dawkins acknowledged that man has, indeed, unique qualities. After mentioning “the ability to plan ahead using conscious, imagined foresight,” Dawkins added: “Short-term benefit has always been the only thing that counts in evolution; long-term benefit has never counted. It has never been possible for something to evolve in spite of being bad for the immediate short-term good of the individual. For the first time ever, it’s possible for at least some people to say, ‘Forget about the fact that you can make a short-term profit by chopping down this forest; what about the long-term benefit?’ Now I think that’s genuinely new and unique.”
Other researchers confirm that humans’ ability for conscious, long-term planning is without parallel. Neurophysiologist William H. Calvin notes: “Aside from hormonally triggered preparations for winter and mating, animals exhibit surprisingly little evidence of planning more than a few minutes ahead.” Animals may store food before a cold season, but they do not think things through and plan. By contrast, humans consider the future, even the distant future. Some scientists contemplate what may happen to the universe billions of years hence. Did you ever wonder why man—so different from animals—is able to think about the future and lay out plans?
The Bible says of humans: “Even time indefinite [the Creator] has put in their heart.” The Revised Standard Version renders it: “He has put eternity into man’s mind.” (Ecclesiastes 3:11) We use this distinctive ability daily, even in as common an act as glancing in a mirror and thinking what our appearance will be in 10 or 20 years. And we are confirming what Ecclesiastes 3:11 says when we give even passing thought to such concepts as the infinity of time and space. The mere fact that we have this ability harmonizes with the comment that a Creator has put “eternity into man’s mind.”
Drawn to a Creator
Many people, however, are not satisfied fully by enjoying beauty, doing good to fellowmen, and thinking about the future. “Strangely enough,” notes Professor C. Stephen Evans, “even in our most happy and treasured moments of love, we often feel something is missing. We find ourselves wanting more but not knowing what is the more we want.” Indeed, conscious humans—unlike the animals with which we share this planet—feel another need.
“Religion is deeply rooted in human nature and experienced at every level of economic status and educational background.” This summed up the research that Professor Alister Hardy presented in The Spiritual Nature of Man. It confirms what numerous other studies have established—man is God-conscious. While individuals may be atheists, whole nations are not. The book Is God the Only Reality? observes: “The religious quest for meaning . . . is the common experience in every culture and every age since the emergence of humankind.”
From where does this seemingly inborn awareness of God come? If man were merely an accidental grouping of nucleic acid and protein molecules, why would these molecules develop a love of art and beauty, turn religious, and contemplate eternity?
Sir John Eccles concluded that an evolutionary explanation of man’s existence “fails in a most important respect. It cannot account for the existence of each one of us as unique self-conscious beings.” The more we learn about the workings of our brain and mind, the easier it is to see why millions of people have concluded that man’s conscious existence is evidence of a Creator who cares about us.
In the next chapter, we will see why people of all walks of life have found that this rational conclusion lays the basis for finding satisfying answers to the vital questions, Why are we here, and where are we going?

Chess Champion Versus Computer
When the advanced computer Deep Blue vanquished the world champion chess player, the question arose, “Aren’t we forced to conclude that Deep Blue must have a mind?”
Professor David Gelernter of Yale University replied: “No. Deep Blue is just a machine. It doesn’t have a mind any more than a flowerpot has a mind. . . . Its chief meaning is this: that human beings are champion machine builders.”
Professor Gelernter pointed to this major difference: “The brain is a machine that is capable of creating an ‘I.’ Brains can summon mental worlds into being, and computers can’t.”
He concluded: “The gap between human and [computer] is permanent and will never be closed. Machines will continue to make life easier, healthier, richer and more puzzling. And human beings will continue to care, ultimately, about the same things they always have: about themselves, about one another and, many of them, about God. On those terms, machines have never made a difference. And they never will.”

Supercomputer Equals Snail
“Today’s computers are not even close to a 4-year-old human in their ability to see, talk, move, or use common sense. One reason, of course, is sheer computing power. It has been estimated that the information processing capacity of even the most powerful supercomputer is equal to the nervous system of a snail—a tiny fraction of the power available to the supercomputer inside [our] skull.”—Steven Pinker, director of the Center for Cognitive Neuroscience at the Massachusetts Institute of Technology.
[Box on page 54]
“The human brain is composed almost exclusively of the [cerebral] cortex. The brain of a chimpanzee, for example, also has a cortex, but in far smaller proportions. The cortex allows us to think, to remember, to imagine. Essentially, we are human beings by virtue of our cortex.”—Edoardo Boncinelli, director of research in molecular biology, Milan, Italy.

From Particle Physics to Your Brain
Professor Paul Davies reflected on the ability of the brain to handle the abstract field of mathematics. “Mathematics is not something that you find lying around in your back yard. It’s produced by the human mind. Yet if we ask where mathematics works best, it is in areas like particle physics and astrophysics, areas of fundamental science that are very, very far removed from everyday affairs.” What does that imply? “It suggests to me that consciousness and our ability to do mathematics are no mere accident, no trivial detail, no insignificant by-product of evolution.”—Are We Alone?

Every People Has One
Throughout history, whenever one people encountered another, each found the other speaking a language. The Language Instinct comments: “No mute tribe has ever been discovered, and there is no record that a region has served as a ‘cradle’ of language from which it spread to previously languageless groups. . . . The universality of complex language is a discovery that fills linguists with awe, and is the first reason to suspect that language is . . . the product of a special human instinct.”
[Box on page 59]
Language and Intelligence
Why does human intelligence far surpass that of animals, such as apes? A key is our use of syntax—putting sounds together to make words and using words to make sentences. Theoretical neurophysiologist Dr. William H. Calvin explains:
“Wild chimpanzees use about three dozen different vocalizations to convey about three dozen different meanings. They may repeat a sound to intensify its meaning, but they do not string together three sounds to add a new word to their vocabulary.
“We humans also use about three dozen vocalizations, called phonemes. Yet only their combinations have content: we string together meaningless sounds to make meaningful words.” Dr. Calvin noted that “no one has yet explained” the leap from the animals’ “one sound/one meaning” to our uniquely human capacity to use syntax.

You Can Do More Than Doodle
“Is only man, Homo sapiens, capable of communicating by language? Clearly the answer must depend on what is meant by ‘language’—for all the higher animals certainly communicate with a great variety of signs, such as gestures, odours, calls, cries and songs, and even the dance of the bees. Yet animals other than man do not appear to have structured grammatical language. And animals do not, which may be highly significant, draw representational pictures. At best they only doodle.”—Professors R. S. and D. H. Fouts.

“Turning to the human mind, we also find structures of marvellous intricacy,” notes Professor A. Noam Chomsky. “Language is a case in point, but not the only one. Think of the capacity to deal with abstract properties of the number system, [which seems] unique to humans.”

“Endowed” to Ask
Concerning the future of our universe, physicist Lawrence Krauss wrote: “We are emboldened to ask questions about things we may never see directly because we can ask them. Our children, or their children, will one day answer them. We are endowed with imagination.”

If the universe and our being alive in it are accidental, our lives can have no lasting meaning. But if our life in the universe results from design, there must be a satisfying meaning to it.

From Dodging Saber-Toothed Tigers?
John Polkinghorne, of the University of Cambridge, England, observed:
“Theoretical physicist Paul Dirac discovered something called quantum field theory which is fundamental to our understanding of the physical world. I can’t believe Dirac’s ability to discover that theory, or Einstein’s ability to discover the general theory of relativity, is a sort of spin-off from our ancestors having to dodge saber-toothed tigers. Something much more profound, much more mysterious, is going on. . . .
“When we look at the rational order and transparent beauty of the physical world, revealed through physical science, we see a world shot through with signs of mind. To a religious believer, it is the mind of the Creator that is being discerned in that way.”—Commonweal.
