>But if we have the capability to destroy another civilisation 120 light years away, then we also have developed far beyond the need to, and they will know that just as well as we will know that. That is a huge leap of faith and operating under a lot of assumptions not the least of which is that a completely alien intelligence would somehow operate in a utopian Age of Enlightenment and moral way and not in a way that we can’t even imagine or even understand because they are completely alien to us. I’m of the opinion that intelligent life is probably extremely rare (in the one place where we know life exists it took 20+ million species and a full third of the age of the universe to make the single intelligent life we have…and we do our best on a regular bases to make ourselves extinct) and that is a damn good thing because I cannot see how intelligent alien life wouldn’t be completely hostile to other alien life and not immediately skeptical of the other’s motivations.
