It may seem like I'm ignorant/arrogant, but I know there are an insane amount of planets in our galaxy alone, and that there are a helluva lot of galaxies, but has anyone here ever seen an alien? I doubt it lol. But anyways, if you think they exist, do you think most are more complex, or less complex, and do you think they walk among us? What do you think they look like, like humans, albeit a bit stranger, or are they giant green beings who are going to suck out our brains? Big or small? Nice or mean? Would they want to kill us all, or befriend us? If you think aliens exist, what do you think they are like??
