Yes, in this universe, life as we know it is a salmon of order swimming up the waterfall of entropy, every flick of it tail powered by its shit fouling the river, because life in this universe is spec'd to the constraints of this universe. But perhaps we can't find the aliens because they have tunnelled out, off to another gentler universe where they grow forever in n dimensions of time and space pondering the beauty of all the integers.
