When I was small I thought that my parent's car didn't move over the Earth, rather, that we kept going straight and the world turned itself to accomodate where we were going. Then I factored in that there were cars travelling in the opposite direction and ones even turning when we weren't. I was then forced to believe that the world itself was just a giant rubix cube turning and rotating itself all at once so everyone could get where they were going. Eventually I figured it out.
