Not all of them believe in germ theory, either. You know that one guy who keeps making accounts, and then saying he's never coming back? He literally thinks germ theory is a lie.
@Pikachu I've heard some of them don't believe in gravity. The justification is that since the world is flat, and there's no such thing as outer space, things naturally fall down toward the bottom, and it has nothing to do with spatial curvature.
