@Zardoz,
The simplest explanation by far is that millions of years of evolution are responsible rather a multi-complex god appearing a few thousands of years ago and creating the world and everything in it in a week. You cannot be logical and believe in the supernatural. You have to choose logic or superstition.

I have issue with the above, since earlier in the post you claim that religion is the metaphoric dinosaur, yet then this arrives, the belief that the root of intellectual debate RE: creation is well and truly rooted in evolution..
That a portion of energy set about certain directions or indeed in certain chosen ways is clearly the startpoint inside the universe, all that remains is the eventual conclusion that the absolute smallest components of reality, which perhaps are smaller still than here, outside the universe, are aware when combined or flowed past each other in the correct patterns. This clears up your statement, to my surprise, yet still man is so flawed that both you and I fall victim to appearance if not careful around the base of evolution theory when discussing dual concepts such as Earth out and universe down.
Evolution is the abandonment of that no-longer present in ones needs, therefore it follows that evolution occurs with zero input at all, relative to itself, by all evolving, when all evolving merely choose any other thought or action.
