'Are we a simulation?' I think the idea is quite philosophical.
We can't say that this substance exists until we directly check it, and the calculation in the game is similar to this. lol
So simulation theory is what we are talking about the laws of reality that can be simulations.
Anyway, this cannot be called the absolute truth, and I think it's a fun topic.
I think it's similar to the story of 'Brain in a Barrel'.
