David Wolpert Proved Absence of Biblical God

https://plus.maths.org/content/inferring-limits-reality

basically, David proved, that there can't be two gods, both having free will to influence the universe anyway they want. That means, the biblical God is not all powerful, because he cannot create another God as powerful as himself. So if there is God, he will be very limited in what he can do and know.

The idea of an omnipotent god is contradictory in many different ways.
If there is a god, it must be more like a programmer, who has limited time and resources, than an infinite being with perfect knowledge.

But a better explanation is that all religions are just mental crutches for brainlets.
