lunamoth--ty for the welcome, I'll try to explain.
I try to use Occam's razor when thinking about major things like this.
The most simple explanation, the one that makes sense, that's rational, seems like it'll be the right one.
Does it seem more likely that there is a complicated set of ethics governing the morality of every form of life in the universe (10 commandments, 5 pillars, etc), or a more simple code? I would say that God could be cut out of the loop entirely, except that there's the issue of free thought. There has to be something more than physical matter when the matter of thought is involved.
In terms of a Godhead, is it more likely that God is a manifested being, as a physical being that manifested itself and died for us, or as a force, a fundamental force. Not only does God not exist per se, it can affect everything.
A God that existed in a set form, or even with an at all-complicated set of ethics, would be a totally unbalanced concept--why, of all the life on all the worlds, would a Godhead take the shape of a human male? It wouldn't fit.
My evidence for a God of this form is just anecdotal. Life exists. Life perpetuates itself. Entropy exists, entropy is balanced by the force towards life--life in the sense of order, not just of life as a biological matter.
It makes sense to me--and I can believe it, not just have faith in it. For me, that is the key.
