“In God’s scheme what is a few billion years here and there. Perhaps there have come and gone a dozen human civilizations in the past billion years that we know nothing about. And after this civilization we are living in destroys itself, it will all start up again in a million years when the planet has all its messes cleaned up. Then, finally, one of these civilizations, say five billion years from now, will last because people treat each other the way they ought to.”
