I think, when asked how life started, an evolutionist would have to say "We don't really know."
What's interesting here is that in order to begin a theory like this, one must first reject a Creator, then comes the conjecture.
I don't think that's true at all. The existence or non-existence of a Creator is wholly irrelevant to evolution. Could evolution work with a Creator? Sure. Could evolution work without a Creator? Sure. The fundamental point is that evolution does not talk about how life arose, only how it changes.
BUT it definitely wasn't created" should finish the quote. Evolution as an explanation to origin to life on this planet is athiestic, meaning God is not considered. The theory makes no real statement reagrding God whatsoever, but is clear that it explains everything with or without a God. Evolutionary theory is not trying, actively, to get rid of God, but for all practical purposes that is exactly what it does - explains away God to those who chose not to take the time to investigate the issue themsleves.
