Answer Quotes - page 100
However difficult those simple beginnings may be to accept, they are a whole lot easier to accept than complicated beginnings. Complicated things come into the universe late, as a consequence of slow, gradual, incremental steps. God, if he exists, would have to be a very, very, very complicated thing indeed. So to postulate a God as the beginning of the universe, as the answer to the riddle of the first cause, is to shoot yourself in the conceptual foot because you are immediately postulating something far far more complicated than that which you are trying to explain.
