Watch the fucking video you moron. He was answering a question of if he believed that God created everything or man evolved out of nothing.
It was a question about "evolution" of not just man, which deals with just the theory of evolution of species, which is what you are alluding to, but also how the whole universe started, which is another theory as well, The Big Bang.
He is saying that there is no proof either way that "God created everything" or that "For no particular reason, there was nothing, no where, and all of a sudden, everything mysteriously appeared and exploded, thereby creating everything."
On a more personal note, the whole thing of "God" vs "The Big Bang" and "Evolution", for the most part, are about the same. Neither side has "proven" their case ... even though only one side is by their very definition, neeRAB to. Personally, I don't see why they can't both be right and both be wrong.
Go read Robert Heinlein "Job" for an idea of what I'm talking about.
This.
