I don't think God is an explanation at all. It's simply redescribing the problem. We are trying to understand how we have got a complicated world, and we have an explanation in terms of a slightly simpler world, and we explain that in terms of a slightly simpler world and it all hangs together down to an ultimately simple world. Now, God is not an explanation of that kind. God himself cannot be simple if he has power to do all the things he is supposed to do.
