An uneducated father with his educated son went on a camping trip.
They set up their tent and fell asleep. Some hours later, the father woke up his son.
Father: Look up to the sky and tell me what you see.
Son: I see millions of stars…
Father: And what does that tell you?
Son: Astronomically, it tells me that, there are millions of galaxies and planets out there!
Father slaps the son hard on his hand and says, “Idiot, someone has stolen our tent!”
