Oho, that’s a pretty bold statement of belief for someone who can’t prove they’re not a brain in a vat!
More seriously though, there are tons of things that have conflicting evidence or are simply too big or complex to have enough evidence to have definitive proof for, yet we still have to make decisions about them. Like believing that X vs Y is a better governing system (eg democracy vs republic). Or what about questions that aren’t related to proof, like defining and living by ethical standards? Yet most people still find value in “moral” things, and believe that people should do “good” instead of “bad”.
Dang, the time cube dude was right all along
