I know because that’s not part of the theory. Simulation theory doesn’t offer any kind of mechanism for that and it would go against the entire idea of simulation.
On top of that, even if that was the case, then the person running the simulation would be acting inconsistently in a way that prevents us from understanding their intent. That would mean that it’s illogical and that there’s no way for us to actually infer anything about the world we’re in yet we are able to do exactly that.
