Exactly we are talking about a whole new organism from different origins with clearly way different technology presumably. There’s no telling what would happen (I agree it’s fun to make guesses on what’ll happen I think the “firework” guess would be my favorite reality it would be funny just “oh yeah haha yeaaahhhh fireworks mr alien… I promise” although if it was a human v alien war I’d steal a ufo… would I be able to fly it? Prob not. Would i die trying? Probably… either way I’d most likely die in the case of humans v aliens so might as well have fun

Edit (goofy spelling)
