initial conditions led to life as we know it will almost certainly occur elsewhere. Only a few years ago, we had no evidence there were even extrasolar planets. Now we know there are thousands relatively nearby, so it looks like our solar system is somewhat typical for stars like ours and that our star is for better or worse, utterly typical. Ergo there are billions of planets out there in our galaxy alone. The argument that we are the only sentient beings because we haven’t heard from any others is (of course) theoretically possible, but highly unlikely. Given the argument above, it’s far more likely the universe is literally teeming with life at various stages of evolution. But even in our little corner of the Milky Way, we don’t hear from them because they are just too damn far away. One light year is 9.46×10^15 meters. None of our own random EM radiation so far would be more than (say) a thousand watts/m^2 at its origin and most of it far less than that. A fraction of that would actually make it out into space where it would just spread out in a spherical wave front. Let’s assume for giggles that it all does and that our alien buddies are also shouting randomly at the cosmos at roughly the same volume (power output).

(The Bolshevik) sentinel slowly raised his head. But just at this moment the Nice luis Arraez 3 Miami shirt body of my friend rose up and blanketed the fire from me and in a twinkling the feet of the sentinel flashed through the air, as my companion had seized him by the throat and swung him clear into the bushes, where both figures disappeared. In a second he re-appeared, flourished the rifle of the Partisan over his head and I heard the dull blow which was followed by an absolute calm. He came back toward me and, confusedly smiling, said: “It is done. God and the Devil! When I was a boy, my mother wanted to make a priest out of me. When I grew up, I became a trained agronome in order. . . to strangle the people and smash their skulls? Revolution is a very stupid thing!” And with anger and disgust he spit and began to smoke his pipe.
