We worry so much about what or better, how are aliens not getting to us by now. Needless to say we are so arrogant that forget that the answer is right in front of our noses. WE ARE THE ALIENS in this world and that our existence has by now been shorter than 5% of what the dinosaurs lived and roamed on earth. Either we take care of earth or that is it for our short existence.
haha I mean yes we havne't been around for a long time, but it does seem a little lonely outside of this planet
