I don’t know why I never made this connection before, but today I realized how parallel universes could explain the prevalence of so many different belief systems among humans when it comes to religions and gods. It could be because each one of these, or at least some of them, are true in various parallel universes, or ‘possibly worlds’ to use the philosophical term for it.
If this part of modern physics is correct, and I am guessing it probably is, I can imagine that parallel universes exist where not only there are small changes from this universe but also very huge changes. Changes going way back in time, perhaps even to the beginning of time. Maybe even changes to the highest levels of existence and the metaphysical itself.
What if there is one universe in which the Christian God is real, and another universe in which Buddhism is real, and another in which the Hindu gods are real, and another in which the Muslim god is real, and another in which the Viking gods are real? Etc etc. More like there would exist corresponding sets of universes in which each god exists and rules those universes. This could be true for any gods/deities/religions you can think of. Maybe there are some that are totally made up, like Scientology
but for the ‘real’ ones we can think of it in terms of superposition of all possibilities existing simultaneously.
And there would also probably be parallel universes in which more than one of the religions/gods are the case as well.
The Mandela effect already shows a very strong likelihood of two things relevant to the OP here: 1) we live in something that can more or less accurately be called a simulation, and 2) aspects of the simulation can change and in all likelihood this involves branching off of new or different simulations, validating the physics idea of parallel universes / possible worlds.
Within that context, why should we assume there is only one answer to the question “who or what is God?” or “which religion is correct?” Maybe none of them are, the typical atheistic view. Or, maybe all of them are (the view I am trying to explore in this topic here).
There is more involved though, including the idea that human belief systems might be creating the deities themselves or might be retroactively constructing the universe in a way that makes that religion the correct one. That seems absurd to me, but I cannot entirely rule it out either. If a large enough group of people hold a certain belief, is there a kind of quantum power enacted here that may cause a split universe to appear in which that belief is true? I don’t think that necessarily makes total sense of course, but in the context of quantum physics and the idea of possible worlds it cannot be ignored unless it can be refuted. And again within this context I am not sure if it can be refuted.
Another possibility: the various religions are “residue” (a term for leftover changes from former universes many people no longer remember). These are embedded culturally-historically and so continue to exert mundane influence over worldly affairs and human beliefs.
Maybe the way our world looks to us would be clearly indicative of one religion being the correct one in this universe, if we could step outside of our universe and view lots of other ones to compare. Maybe there is a kind of very higher level analysis and theory which would be able to look at aspects of our world and say “Ah, yes, in this universe X religion is the correct one, because of these features…” meanwhile the other non-true religions that still exist in this universe go on as normal with lots of people still believing in them even though they are not true. And again there would exist a very large set of universes for which this is the case. Then on top of that, there would also exist other large sets of other universes in which a different religion were the true one for that particular universe, and maybe in those universes our world happens to look meaningfully different from what we are used to in certain key ways that, on the higher level of theoretical understanding of a more ‘cosmic anthropological level’ would make perfect sense.
