People beilive that aleins do live in the world and in our galexy. Who knows.. They could be living on venus , mars , or maybe even pluto or even earth.. Maybe they look like us. Maybe they dont have green skin or big heads.. Maybe their just like us but speak and look a little bit different. We could be taller , or thay could be a size of babys. But we know very nothing of aleins yet. We just have to see in the future in aliens are our friends , or enemys
