If the American continent was empty of human life except for 2 individuals, the likelihood of them ever meeting would be minute. Now expand that into a universe that is infinitely vast. Even if life exists out there (which is definitely possible), the likelihood that we would ever meet or even be able to recognize something as sentient life and actually communicate with another form of life is staggeringly unlikely. Saying that, were we to meet a fellow sentient space faring species the chances that this meeting would result in anything other than utter extinction level disaster are equally slim. All life follows a similar pattern. Find resources, occupy a territory or area, consume resources (including other organisms) multiply. This notion of searching the universe for life to shake hands with is naive. By all means, scan the horizon. But if you spot something you have to either hide and pray it didn’t see you or you meet it head on and fuck it up so bad it never comes back…. If you can do the latter, then the only sensible option then is to follow it home and consume it. Because the rules of life dictate that it WILL return eventually.
