No, We Probably Don’t Live in a Simulation
Jan Haugland

The debate isn’t really about whether or not we live in a simulation. It’s about whether or not we could tell the difference.

In a “universe” that could accurately track the “laws of physics” to the highest possible resolutions capable with our in-universe “instruments” (and then provide escape hatches like “quantum mechanics” for those places beyond which you don’t want conscious beings to peer), the only material difference would be the existence of God (the builder of the simulation computer).

So far, we haven’t been able to prove (or disprove) that.
