It’s not a belief because there’s not an absence of evidence. There’s quite a bit of evidence for it. Whether you agree that it’s compelling is another story. Also, no one “believes” in simulation theory. It’s simply a theory to explain our current understanding of the world. In the same way that no one “believes” in the theory of gravity. It’s just a possible explanation of what we observe.
