How about thinking about this:
For man to gain more and more consciousness of the world around him Gods became his tool they became his way of making sense of the world very early in this process. Hey we can logical see why early man and his projections made so many gods, like the sun, the planets, the milky way the tree, human emotions, etc...
So psychically we have perhaps millions or hundreds of thousands of years in the human development of the God image. I do think there are pitfall to an Atheists psychic state when he is too one sided especially when this attitude is a modern one and out of whack with eons of human psychic evolution.
But also one views of Deity or deities has profound effects on one psychic growth and formation of ones shadow and strongly effect them for good or bad depending.
