At least the "God" of the Old Testament. Now a "creator" god can never be ruled out, but if you'll notice it's domain has been pushed back from the Earth and stars to the Big Bang, and there may have been many of those.

Having said that, dark matter and dark energy could occupy as much as 97% of this Universe's mass and energy. Maybe "God" is resident in there someplace.

But the "God" being channeled by the prophets sure doesn't seem to have left any objective trace, and there's been a lot of looking. Not for "God", but at what is there.

And sometimes folks will believe anything which can give order and structure to a confusing world. The Jewish religion talks about a "holy anxiety", the realization that Man will never understand "God" and it's arrogance to even look.
