I didn't say that the hypothesis of an omniscient, omnipotent, omnipresent creator was falsifiable, I said that some of the claims made by those who believe that hypothesis (Abrahamic religions) are demonstrably false.

I then contrasted that with the simulation hypothesis, that doesn't make such claims.

That doesn't make the core hypothesis of either one falsifiable. Rather, it (at least to me) makes me less likely to entertain the (non-falsifiable) hypotheses that surround themselves with demonstrably false claims than those that don't.
