My first theory :)

                                           Aliens

              I have a question, why do people interpret aliens to look has if they have weird head shape, big eyes, and a small mouth. For all you know they could look exactly like us. Thats beside the point, what if this very minute these aliens come to earth. Would they hurt us? or also be scared just like how we are scared because they probably look at us as aliens also? I believe we won't know until they come to earth or if we find them. I also believe they won't attack the earth because they probably don't know what we are or what we do. What if they have more advanced technology than us? maybe we can make peace and fix this world a bit? well that is just a theory. Hope you enjoy ! k bye.
