I used to believe that each person/family in the world lived on a different planet in the solar system. My family and I, for example, lived on Earth, while my friend lived on the moon. Another friend of mine then, quite obviously, lived on Mars, and so on. I realised this was wrong when I noticed I was able to visit my friends at their houses without any help from NASA.
