A clue as to where life started surely comes from noticing a peculiar coincidence: the Earth-Moon system is a freakish double-planet system. Round about when life began, the Moon was very much closer to the Earth, and a day much shorter (4 hours?). Tides, twice a day, would have been enormous. The perfect mixing cauldron for banging chemicals together until something interesting happened. And here life is found. Coincidence?
