Suppose that something like the simulation theory is correct. Just as in the future we’ll be creating simulated universes, so we may ourselves be in one right now. The simulators don’t really care about us or how our lives go, and they may have all sorts of strange reasons for creating the simulation. Also, they are limited in power and knowledge, so while they can do amazing things like end the universe whenever they feel like it, or produce a flood or hurricane just like that, they don’t know exactly how many people will be killed in the flood or exactly what the consequences will be.
Now, the question is, does it make sense to feel grateful to these simulators for creating such a cool universe? My own view is that it does. The theist seems to think that these feelings are rational only if they’re directed towards a perfect being, but why should this be so? Why not have a religion about imperfect beings? After all, if I created a simulated universe, and the creatures inside it decided to start a religion thanking me for creating their world, I don’t think it would be so crazy. They don’t need to tell me how great I am or how I never make a mistake. They just want to say thank you for creating.
