God - does S/He exist...

I've been thinking about this recently, or rather, I should say I've been thinking about atheism. There are two reasons for this. (1) I consider myself to be one. (Atheist, that is, not God). (2) I 'm reading Richard Dawkins' "The God Delusion". (3) I know, I know, but everything is mutable - my partner P is an agnostic.

Now to take 3 last, P says she is an agnostic rather than an atheist because she doesn't know if there is a God or not. Further, she claims that if the Universe is a construct, then its creator is for all intents and purposes God. Now I can't know if there is a God or not, but I feel that I don't know it at the same level that I don't know if there are ghosts or fairies. If God is as wraithlike and insubstantial as these creatures then so far as I am concerned he doesn't exist. Conversely I might agree that the universe could have a creator, although I think there is sufficient knowledge of quantum mechanics to suggest that we don't have the intellectual machinery to cope with what is beyond the universe. And I say "beyond" for want of any better word. Anyone who is viewing the universe as being "somewhere" hasn't grasped the nettle. If the universe does have a creator, however, that doesn't make it a God in the conventional sense.

My atheism, then is this :-
1) There is no supernatural being (fuzzy creator or white-haired old man don't care which) who created the earth and takes a specific interest in it.
2) The Bible and its content are human constructs.
3) Religions are, in the main mechanisms for controlling people.
4) Praying in all its manifestations is only useful as a form of meditation or emotional comfort.
