Why doubt the God concepts so far?
The silence of the Gods is strong and the proud,loud, diverse, contradictory, and extraordinary claims of humans who speak for the Gods is anemic and that is why I doubt the existence of their Gods. The human claims are many and the evidence is little more than a non sequitur.
A long view of history should make one cautious to believe in the God of the moment. Changing, morphing, adapting, and hybrid religions are common in the history of human civilization.
