Which I would say would be true but I have lived long enough to see what was true become incorrect and then false. Non-political/religious ones; dinos from reptiles to dinos to birds, and comet impact with planets, Columbus was the first European in America. Give a belief enough time and it could become truth. What is crazy, to some, no matter how many facts, they will not change their belief.Nope. Ideally people would believe reality but that's not necessary for reality to be, well, reality.
