If the universe is continuing to expand as they say, there should be "life" somewhere else. Why don't they visit if they have interstellar travel capabilities? Probably sitting out there by the moon with their cloaking device on going.."What a complete bunch of tools those humans are....racist...greedy...self-destructive. Let's use this planet as an example of what NOT to do." Our species is just probably not mature enough for contact yet...after admining for a while, I think they are right!
