Hi naomi - I've said it before: it all depends what you mean by 'God'.
I'm a Pantheist, i.e. I believe that God and nature/cosmos are the same thing, but that there is more to it all than matter and energy. I believe in evolution, for example, but believe it is not just an accident. The universe and all its marvels didn't just come from nothing without something behind it. Yes, there's more than just matter and energy. There's the great unknown and unknowable 'why?' as well.
This force, of which everything is part of, I like to call 'God'. The problem is that whenever the 'G' word is mentioned, everybody assumes you mean a man in the sky. Some people do imagine God in that way, but they're not 'wrong', because it's 'right' for them. That's their interpretation.
So what I believe in, you might not call God because it doesn't fit with your definition, but I do. I prefer to.
Cheers, dudette.
