No one has been able to prove a negative, nor has anyone ever proven the existence of god. There is no way to settle the question unequivocally.
Yes, there are difficult questions to answer, and science will never answer some of them. It has answered the question of how life was created, but can't even address the question of who did the creating. Science can't tell us why we exist, whether we will continue to exist after the death of our bodies, or what that life might be like.
So, we human beings create religion, based on a belief system that has no scientific evidence behind it. It is comforting for some to think that we know the answers to unanswerable questions. Others see the belief systems as shams, and then conclude that there is no creator. That is yet another belief system with no scientific evidence to back it up.
Still, if the existence of creation isn't evidence of a creator, what is?
Does the existence of a jetliner prove the existence of a creator of said jetliner, or are we to assume that it simply evolved from simple machines and has as its ancestor the Wright Brother's aircraft? Of course, we know that there is a creator, us, and that it did evolve from simpler machines. Evolution, then, doesn't explain the existence of life, just the means by which it came about.
