Sherlock Holmes and Dr. Watson decided to go on a camping trip. They pitched their tent under the starts and went to sleep. In the middle of the night, Sherlock Holmes woke Watson up and said, “Watson, look up at the sky and tell me what you see.”

Watson looked up and replied, “I see millions and millions of stars.”

Sherlock said, “And what do you deduce from that?”

“Well,” Watson continued. “If there are millions of stars and if even a few of those have planets, it’s quite likely that there are some planets like Earth out there. And if there are a few planets like Earth out there, then there might even be life on other planets.”

Holmes replied, “Watson, it means that somebody stole our tent.”
