I can't even prove to you that I myself am sentient. And as far as I know I might be the only sentient being on earth and everyone else are just faking it. There's just no way to know right now since we don't know what sentience really is. Therefore it's a bit of a moot point when talking about simulations, since you're asking about something we can't do in ANY universe right now.
