I wish this were aliens. I really do. First Contact is a philosophical dream. Imagine the Catholic Church trying to reconcile the existence of extraterrestrial life with their own Earth-centrism. Or imagine people like me, who are anti-human-presence-in-space, having to eat our words as the aliens took us on sightseeing jaunts across the galaxy. Or imagine the philosophers, writing about existence, having to rethink human consciousness given that non-human consciousness clearly exists!
Now, the fact that the aliens would most likely be here to wipe us out is another issue.
