what gives me pause is, that with all the juicy organic material around, we have not seen spontaneous, or artificial restarting of the original spark that fired up life.
For one thing, our earth is filled--in every niche, every nook and cranny, from deep sea vents at crushing pressures and temperatures, to arctic permafrost, to hot springs, and everywhere in between--by bacteria that see juicy organic material as food. And if some of those juicy organic materials could avoid being consumed by bacteria, earth is an oxygenated planet, and oxygen reacts with organic compounds and they degrade.
