I made up a theory about history. "The pinhole camera theory of the universe" says that the further back you go in time, the narrower history gets, until it passes through a pinhole and then spreads out again only upside down. Maybe the big bang - if there was a big bang - is such a pinhole, and before the big bang there was a universe full of things like oceans and continents and people living in cities with tall buildings, paying taxes and worrying about their kids. Some of these stories come from before the pinhole, I can't explain them any other way.
