If I ever met an alien I would want to know how they reproduce and how they raise their young. What do they value? Why do they value what they value? Do they have a culture? How do they teach their young? How do they structure their societies? How old is their species? Do they know their full history or have they lost much of it, like us? Do they know of other species around the universe? If yes to the last answer, then I would have a LOT more questions. Actually, regardless, I would have a lot more questions, in general. I would annoy the poor aliens with all my dumb questions😂
