So claims C. Hitchens. No, surely he does not mean that we have created the eternal, absolute, creative power that caused the Universe...
Yes! From the point of view that we have made an image of God and the belief that there is only a representation. This does not, however refute that such an image represents something real, or something that is to be. Nor that this image could be a connection or a channel to the idea of the absolute.
Indeed it is that for many people. Those who believe have some advantage in their lives. Recourse to solace, serenity and trust, reminder to connect with fellows as brothers and sisters. This pragmatic argument however could be , anything useful for a believer could be useful for another and in another's hand - a source of abuse.
Without an actual god we could still have a sense of wonder at the spectacular world, but do we need to the euphoria if it is just us at the top of the heap?
