Yeah, the only conception of God that has ever made any sense to me is to define "God" as the totality of the universe itself, that is, the sum of all the matter and energy that exists. I don't object to that definition of God at all. I see no problem with having reverence for all of existence. After all it is a grandiose and beautiful thing. And it's even been proven to exist to boot. But I choose not to call it God because it's nothing like the non-physical spirit thing most people take that word to mean.
