However, at this point you would do well to consider, Did God’s purpose for the earth and man change when Adam and Eve sinned? You will find that no one can point to a single Bible passage that says so. To the contrary, many years after the first human pair sinned, Isaiah the prophet was inspired to write:

“This is what Jehovah has said, the Creator of the heavens, He the true God, the Former of the earth and the Maker of it, He the One who firmly established it, who did not create it simply for nothing, who formed it even to be inhabited.”

Isaiah 45:18

You can see that the Bible thus clearly states that God, in creating the earth, made it a permanent fixture in the universe and that his definite purpose in creating it was that it be inhabited by humans. That purpose has not changed. God will see to it that his purpose will be completely fulfilled.
