From a Nova video, "Origins How Life Began", at https://www.youtube.com/watch?v=G8cRr3NkpLA
"Life began as a chemical act. Life is really chemistry. There is no question about that. In fact it's a chemistry that when you get the recipe right, it goes and it goes fairly quickly."
How life got a foothold on Earth about 3.8 Billion years ago is a favorite hiding place for the god of the gaps. But there are no gaps. The fairy's magic wand was never necessary for anything.
