The theory does not at all reject the concept of God. It is a simple description of mechanics as well as we can determine them to date.
I have tried to tell GodGunsGuts the same thing many times. He refuses to reason. The Big Bang theory was originally rejected by scientists because many thought that it sounded too close to what the Bible describes in Genesis. In fact, the name "Big Bang" was used to mock the theory, but the moniker stuck.
In the meantime, people like GodGunsGuts make it very difficult for we Christians who happen to be scientists to witness to others in our field. The wacky theories and flat-out lies by Young-Earth Creationists turn off technically-educated people and they assume that all Christians are stuck in the Dark Ages.
For example, assume that Ahmadenejad understands economics well and suggests tax cuts to help the American economy. No one will listen to him because he's so whacked out in other areas of his beliefs. Same with the Young-Earth Creationists. They prey upon gullible people.
