Part I Begins

Upon further reflection and a seminar by one of the experts on the Clay Mineral Hypothesis, I've realized that a little bit of the science here is mungy (i.e., how did photosynthesis work 3.8 billion years ago?) or I've given a little more impression of certainty than is justified by the evidence (i.e., Late Heavy Bombardment). So I'll try to get back to revising things after I take a little time to let Lent begin. If you've been linked here by Fr Kniseley etc., please enjoy the Context and Preface below.
