It does bring up the interesting conundrum: is there one "base" universe? Then how did that start? Makes no sense. Is it turtles all the way down? That also doesn't make any sense. And yet those are the only 2 possibilities (assuming a few intuitive things about logic and reality, which is a whole 'nother thing...).
Hypothetically, isn't there also a third option that one eventually gets to a base universe, but that base universe has existed for an infinite amount of time and has no beginning?
I know it's a few days later now. But I'm agnostic and not explicitly atheist and the reason is that, one of the few scenarios that made sense to me, I never thought of as simulation theory.
It was that the big bang doesn't remove the possibility of a God. That God could just be an alien that exists outside our concept of time and created this universe with the concept of time as an experiment.
I suppose this could be a simulation too. That is, that alien outside our concept of time creates a simulation of a universe with a linear time.
But, you know it's all thought experiments.
Im an atheist myself, though I'll agree, the universe having a beginning does not preclude the possibility that it was created by an intelligent entity of some kind, a simulation is one way this can occur, but not the only one. I dont think such a creator likely, but I cant rule the option out. However, I dont think that an entity like this is really deserving of the title of god, because a simulator (or someone who has some kind of weird tech to mess with spacetime such as to create a new physical universe artificially) is still just as fallible as any other limited entity inside their own universe. Conceivably, if someone discovered a way to cure aging or something within the next few decades, its not impossible tho probably very unlikely that you or I might someday see the technology to create such a simulated universe developed, but if I were to create one, that would not really change what I am at all, or give me limitless knowledge or make me deserving of worship. This might be because I was raised in a family mostly full of Christians and therefore interpret the word the way Abrahamic religions do, but I dont think I could really consider anything less than an actually Omnipotent, Omniscient and therefore limitless and infallible being to be a god, and as I also believe that omnipotence is a logically impossible and self-disproving concept, and therefore, that it cannot exist in any reality no matter what rules may govern it, I feel as certain as I can be of anything that no such thing exists.
I'm using God as a generic term for creator. I do realise it's a loaded term though.
But at that point, isn't that no different than just saying the universe isn't a simulation? If there is a base universe than that is the "actual" universe, and who cares about all the simulations beyond what we would care about a simulation we created? For this to be the case, I feel like there would need to be some additional features or complexities about this base universe that can't be simulated and thus that allows those in it to prove that they are not a simulation. The issue the simulation universes have is that if they could create a simulation of their own universe they are immediately confronted with the conundrum that they themselves are probably not the first one to do this. But this theoretical base universe would have some characteristic about it that precluded them from this issue. Or maybe they don't, maybe they think they're simulation too but they're not and have no way to prove otherwise, they just happen to be the base. However, if that is the case, then you can make that same argument for this universe can't you?
I don't personally suspect that anyone could truly create a simulation of their own universe at all. You could absolutely simulate a universe, but simulating your own universe (presumably your own universe at a point in the past since that's what context the simulation argument generally gets made in) would have to have some kind of deviation from the real universe, be it that not all of the universe is simulated, or it's only simulated to a certain level of detail or "resolution" and any physics on a smaller scale is simplified, or time runs slower or something. Because if you can simulate a perfect copy of your universe, or a universe of equivalent complexity and speed, then you can build a computer in that simulation equivalent to the one running it, and since that simulated computer doesn't use all the resources of it's simulated universe presumably, you can build several of them and get more processing power than you started with, which makes no sense. And if every "layer" of simulation inheritly has dramatically less possible complexity to it than the layer above, you should eventually (and I suspect rather rapidly) reach a level where further nested simulations are not possible
