Is it not possible, that we, humans, are actually aliens? Maybe we came from a different planet, and our different "races" and "languages" are because we are from different galaxies/planets? I've always wondered... Or perhaps "aliens" from another galaxy are using us as test subjects, to see how far we will evolve, and how complex we will become. I believe that in ancient civilizations, these "aliens" have come to our planet and have helped/taught our ancestors basic fundamentals of physics, math, science, medicine, etc. Like, how would humans with little to no technology could have built pyramids and other huge structures? I can't simply believe that. And what is our purpose as humans? Being more intelligent than any other organism known to us? Or is there no purpose? We are simply a parasite, a cancer, to this Earth. We take from this planets natural resources, and turn it into chemicals, and poisons, and pollution. Slowly killing the planet, if you will. We're here, to fuck shit up.
