I appreciate your deep reasoning. But let me digress.
As for the God thing, I see that as emanating from the base ego. as a secondary impulse. To me the base ego's primary mandate is to survive at all cost and to seek advantage at every opportunity in that endeavor.
Moreover, so powerful is that survival impukse that it causes folks to even contemplate somehow existing beyond the flesh. Thus the concept of God or Gods, with some sort of heavenly afterlife, comes alomg for the ride.
Now I also see an evolved intellect as a force to tone down the rather crude ego, Thus folks like Trump who are quite devoid of intellect, and most of his supporters as well, not including those who are behind him for reasons of economic or power advantage, come off as crudely egotistical.
