I want to tell you a joke and see if you think it is funny.
The joke is:
NAME_1 and NAME_2 are camping. They are atop a hill, laying on their sleeping bags and staring at the stars. 
NAME_2: NAME_1, do you notice anything?
NAME_1: I see stars in their uncountable billions of billions strewn across the sky.
NAME_2: And what can you conclude from that observation?
NAME_1: Well, with so many stars in the universe, some number of those stars must be suns just like our own. And some number of those stars must have planets, some of which are just like Earth. NAME_2, we are not alone in the universe!
NAME_2: NAME_1, you idiot. Someone has stolen our tent.
