 Richard Dawkins begins "The God Delusion" by making it clear that the God he talks about is the Abrahamic concept of a personal god who is susceptible to worship.He considers the existence of such an entity to be a scientific question, because a universe with such a god would be significantly different from a universe without one, and he says that the difference would be empirically discernible.Therefore, Dawkins concludes, the same kind of reasoning can be applied to the God hypothesis as to any other scientific question.
