No false modesty, I actually teach it O.K., but the real secret I think is that if you tie real information to a story about their origins, people just eat it up. You get this whenever grandparents can be persuaded to tell their grandchildren the history of their family in detail. It seems to go straight into the soul: the craving for some real hard factual truth about where we came from: not bullshit, the real thing, with the gaps left in if there are true gaps, and so on. And coherently: a story whose end is here today. The Earth Story is just one of those.
