An awful lot of people spend an awful lot of time telling us how many other planets have life on them. They never tell us which planets they're talking about, though. They never tell us if these other planets, the other ones with life aboard are in our solar system, if they're in the Milky Way or any other galaxy. They never tell us if there are other forms of life within our universe or any other universe, if there are other ones. What do people think? Is there more life out there? Are there other universes where life could exist - or are we really the only ones that actually exist?
