Aliens, who doesn't believe in them? The possibilities of them existing are pretty big, anything can be out there in or outside of our universe, as of now you're currently chilling by the forest behind your home, laying on a little mount watching the stars, then you see a shooting star! What a good night, but, that shooting star is getting awfully close, and then, it crashes by the forest, now, you could ignore that and keep stargazing, ooorrr you could go explore it! And you go explore that, and turns out it's an UFO, you found aliens!!! The UFO was huge, and i mean it, like the cockpit was really big and tall, but then an alien comes out, it's a huge slug alien, it has feline characteristics too, like a short muzzle and a thick slug-cat tail, and also four eyes and six freaking arms, she turns to face you and starts speaking, but it's alien gibberish, you don't catch anything at all, she catches on that, and suddenly kisses you, not a peck kiss, but a french one, after that little thing, she speaks in perfect english.
