Actually, Dawkins is in a loop in this argument - he's attempting to turn Creationists' arguments back on themselves.
He, as many of the anti-Creation argue-ers do, doesn't see that he has the same problem at the point of the Big Bang. ( would you call it BB Prime, Alpha or Number 1?)
Well, you could call it the Logos of the beginning....
How many Big Bang theories are there by now, or do all these names refer to the same event?
Thanks for the ping, Hocndoc!
