For how the energetic cycles of that power the cell emerged, that alone has only entertained many interesting possibilities, hot core and cooler oceans, reducing ocean/sea floor/land and more oxidizing atmosphere, molecules generated by incubation in space and subsequent infall to earth, reacting with terrestrial molecules, photochemistry (from a uv-rich sun), concentration gradients of a wide variety of sorts, reactions of molecules produced by energetic processes involving meteor impact/burnup.
