Sherlock Holmes and Dr Watson go Camping, and pitch their tent under the stars. During the night, Holmes wakes his companion and says, Watson, look up at the stars, and tell me what you deduce. Watson says, I see millions of stars, and even if a few of those have planets, it's quite likely there are some planets like earth, and if there are a few planets like earth out there, there might also be life. Holmes replies, Watson, you idiot. Somebody stole our tent.
