if there is no evidence suggesting it as a possibility
100 years ago there was no evidence that you (and everyone) would have not just a phone, but an actual computer in their pocket. "balderdash!" they would have said if you suggested it. "preposterous! impossible!"
again i'm not saying we ARE in a simulation, nor am i telling you what to believe, but i'm still skeptical of the "it's impossible, proven by my math" claim, seeing as how so many "certainties" throughout history have had to be adjusted--or discarded--due to new developments

there are plenty of things going on in the world that science can't explain. but it happens, without a "plausible pathway by which it could be done"
anyway, nice talking. i reject the "it's impossible" claim
