Even the most astute student of science would have to admit that the concept of where life began on Earth isn't proven. It's just a theory. We've seen evidence of evolution, so we know evolution exists. However, there is no second successfully reproduced experiment of Earth to see if the theory is correct. We keep finding potential candidates, but none have proven the theories yet.

At this point, the omniscient creator is not any less provable. While it might sound ridiculous, there's no more proof for other ideas. After all, even if you subscribe to the Big Bang, where did all of that mass that went Bang! come from?
