I think we definitely should be allowed to add things that haven't been mentioned or demonstrated, but only if they're very obvious. To go by the stricture of saying if it hasn't been demonstrated then it's not true, is flawed logic. As otherwise, we'd be believing thing such as shapeshifters are not stronger than mosquitos seeing as we've never seen them fight before and other crazy things.
