There is desire to rely on higher power. I think that was likely a survival advantage that enable our young to be more pliable and manageable by their parents and tribal elders, and made them more willing to take instructions in life lessons from their parents and tribal elders. So evolution bred that into our genes.
I suspect this desire would be reflected in some genetic based endorphin reaction when one thinks one is being looked after by a power stronger and wiser. When one reaches adulthood, look sound, and see others are no longer stronger and wiser, one might be subtly tempted to continue to receive this endorphin high by imagining a even higher and wiser, but unobservable, power that continues to look after one. To make the vision more convincing still, one even transfers many human qualities of those who really had been stronger and wiser when we were young to this new imaginary sky guardian.
