Interesting discussion,

Humans as a species have shown over the centuries that we have an over inflated opinion of our own self importance as shown predominately by the indifference towards other religions and nationalities than our own

Whatever the truth is, be it an alien species or a military/technology arms race or some unknown yet to be discovered physical dimension/phenomenon there are going to be a bunch of frightened, worried people eating humble pie when it's shown to the world they are not as clever as they think they are
