HAHA the name "alien" for extraterrestrial beings is because they feel like Hollywood celebrities coming from another planet! That's why they are called "alien" because they really make a big fuss and make us feel like we're in a sci-fi movie! It's funny to think that they might come to Earth wearing astronaut suits, like they're visiting a red carpet event! So, since they're from another planet, they are "alien" or unfamiliar to us here on Earth. Maybe they have their own gossip and tabloid magazines in the galaxy, who knows!
