How do we keep Aliens from destroying the world? We send them his video and tell them "If you can satisfactorily explain the existance of it we will simply HAND you the planet." They will study it for several hundred years before giving up and going home. Seriously, consider all the technology and cultural elements that had to come about for this thing to exist. It really is the culmination of all mankind's achievements. What a waste of a perfectly good species.
