I definitly think there are forces out there, or "higher powers" that we don't understand, either by the limit of our brains, or by our lack of knowledge we have thus far. As humans, we are limited to what we know and are discovering new things all the time. So there are definitly uncharted areas and new levels of conciousness beyond are ability to comprehend. So I guess you can refer to that as "God" because it is a power higher than us.
But what I DON'T believe God is is a human-like figure up in the sky who watches over everything we do, has a concious mind, answers our prayers, bends things to his will, etc... I think that's a very simplistic view and is nothing more than a cop out for people that try to understand things that we can't understand.
