Well you are in a way, what is a simulation ? It's just a set of rules you follow that are simpler than the more complex environment that it runs in: I suppose if we could "see" "outside" the "universe", we'd understand that maybe our reality is very simple and limited compared to the "reality" outside. Maybe this would be true infinitely, or maybe the outside reality would be much more logical than ours, and we'd accept it's finite.
But since we have a beginning, and a flow of time, we probably also have a birth, a mother, and maybe even a purpose... but that's a very human way to think, might all just be random soup.
But imagine there's a self-aware agent in a simulation we create, he starts thinking the same thoughts, everyone mock him "we're all just random, there is no God, no design, how could so much energy be spent on such a useless giant block of empty space for any reason", he would have to sort of agree, but he would be sort of wrong. And discovering us, would bring him no solace: we can't tell him of our own designers ourselves. Discovering them, would bring us no solace either, for the same reason. That's why the concept of God is stupid: God has a God too, so what do we do now, solved no problem to accept His existence.
That concept of God is stupid, some are tautological, and some are experiential. Eg the concept of God is love (if you have faith in the concept and reality of love being real).
I think modern people have so much faith in this reality, they'd have little chance accepting that it is other than it seems. Any evidence would have to be stark.
Actually, physics supports the probability that we live in a simulation. Our universe has the highest limitation of speed and the smallest units of length and energy.
Neuroscience, psychology, public opinion polls, and internet forums demonstrate that we do.
The problem is, the nature of this style of simulation, as opposed to the Bostrom theory ("the" simulation theory (singular, there can be only one)), makes it (nearly) impossible to realize.
This is both tragic and hilarious, especially since we have extensive knowledge of this flaw.
When thinking about this one, I always wonder if it even matters.. playing both "Yes" and "No" scenarios doesn't really offer any insight for me. Maybe it's a degree of nihilism but it makes me not get overwhelmed.
God created electromagnetism as a way to transmit power between the fusion plant and its simulated planet, and is now delighted that we also use it to trade Pokemons back and forth.
