The notion that given enough time, somehow, someway, things can be created without a Creator.
Well, what you said above is a concept, not a concrete statement that one thing evolved into another. If you're going to have an intelligent conversation about evolution, it helps if you don't mis-state someone else's position.
And just so you know, there are plenty of people who believe there's a creator, and that evolution is part of the creation. The two are not mutually exclusive as some would have you believe.
