Unless you are familiar with the work of a German patent attorney named Gunter Wachtershauser, just about everything you have read about the origin of life on earth is wrong. More specifically, there was no "prebiotic soup" providing organic nutrient molecules to the first cells or proto-cells, there was no RNA world in which self-replicating molecules evolved into cells, the Miller experiment is a red herring and the chemical processes it deals with never happened on earth until Miller came along. Life didn't invent proteins for a long time after life first originated. 500 million years or so. About as long as the time from the "Cambrian explosion" to us.

I'm not saying Wachtershauser got it all right. But I am saying that everyone else except people inspired by Wachtershauser definitely got it all wrong. (70%)
