The point was, as I stated, that it doesn't matter.
Evolution is defined as the study of how and why populations of living things change over time.
Abiogenesis, which is much more mysterious, is how nonliving matter became living. Since there are, by definition, no organisms to evolve, Darwin's theory cannot be used. There may have been analogous processes at work, but they dealt with chemicals, not cells.
There is a fair amount of research being done, but no firm results yet.
My own guess is that a lot of questions will be answered when the moons of Jupiter and Saturn are explored in depth.
