Again, being a die hard Theist , another, different way of presenting an opinion will be attempted.
What god is, pertains to cognitive constructions of ideas formed by ritual, based on myth or Reversely, ritual based myth.
There is substance to ritual and myth, and they pertain to both, rational and so called irrational” content. Now reel foreward to modernism and beyond. The superconscious is developing out of superconscious compilation of memory.
It is beyond discussion, that given a survivable time for humanity, super memory-consciousness will eclipse and overcome human memory by many many fold of power.
This will become a repository, not of matter, since by that time all matter may be reducible to pure energy, based on a temporal universal imminence, which would preclude questions about the creation of matter mute and irrelevant to the underlying question of inquiring of what ‘existence is comprised of’. Therefore nothing ever is created or destroyed.
If aGod can be understood as a quantum memory whose set comprises another, then another, approaching small possible sets, then this super repository can curve space time and return to the beginning, which instantly becomes imminently analogous, so near identical with this curve backward, that the perfect ontological perimeter is created, for ever.
Now if this is conceivable, then the beginning, where the word describes the beginning of creation, of belief, may have transferred to primitive man by a conduit, which can only be understood, by higher levels of revelation, then was available back then, which really is still only now, except we understand it as a transcendence.
