Sherlock Holmes and Doctor Watson – Level 3

Sherlock Holmes and Doctor Watson go camping. They put up their tent under the stars and go to sleep. Some time in the middle of the night, Holmes wakes Watson and says, “Watson, look up at the sky and tell me what you see.”
Watson says, “I can see millions and millions of stars.”
Holmes says, “And what does it mean, Watson?”
Watson replies, “Well, if there are millions of stars, and even if a few of those stars have planets, then it’s quite likely there are some planets like ours out there. And if there are planets like earth out there, there might also be life.”
And Holmes says, “Watson, you idiot, it means that someone has stolen our tent.”
