The Universe was a damned silly place at best . . . but the least likely explanation for its existence was the no-explanation of random chance, the conceit that some abstract somethings “just happened” to be some atoms that “just happened” to get together in configurations which “just happened” to look like consistent laws and then some of these configurations “just happened” to possess self-awareness and that two such “just happened” to be the Man from Mars and the other a bald-headed old coot with Jubal himself inside. No, Jubal would not buy the “just happened” theory, popular as it was with men who called themselves scientists. Random chance was not a sufficient explanation of the Universe—in fact, random chance was not sufficient to explain random chance; the pot could not hold itself.
