One would have to assume that if there is life here than there might be life on at least one of the other trillions and trillions of planets. Yet I would be a little baffled at why a technologically advanced culture would travel all across the galaxy to visit some Podunk group of lifeforms who are killing each other everyday. All because they look different from one-another or have differing views, but it is hard to look away from a good train wreck.
