14. When Seth quoted me as referring to a “life cloud,” he went back to the discussion Jane and I had at lunch today, concerning recent news reports and articles: Some prominent astrophysicists, mathematicians, and astronomers have announced their belief in a theory of “panspermia”—that in ordinary terms of time life on earth was “seeded” from space, instead of arising by pure chance in some primordial ooze or sea on our planet. Those men believe in evolution—that once it originated, life, as Charles Darwin proposed, has ever since been growing in complexity and “evolving” through natural selection and random mutations, or DNA copying errors, into the life and beings we see and are today. Among other signs, the rebel scientists cite the evidence for vast clouds of microorganisms in space, and the identification in certain meteorites of bacterial and fungal micro-fossils, along with a number of amino acids. They claim that even at 4.6 billion years, the earth mathematically is not old enough for life to have had the time to evolve (beginning about 3.8 billion years ago) into its enormously complex current forms. That lack of ordinary time in evolutionary theory is a question Jane and I have often wondered about.
