There are more stars in the universe than grains of sand on the world’s beaches.
More stars in the universe than seconds of time that have passed since Earth formed.
More stars than words and sounds ever uttered by all humans who have ever lived.
Each star system is an island in space, quarantined from its neighbors by the light-years. I can imagine creatures evolving into glimmerings of knowledge on innumerable worlds, every one of them assuming at first their puny planet and paltry few suns to be all that is. We grow up in isolation. Only slowly do we teach ourselves the Cosmos.
