Life from an inorganic is tricky. Judging from the timeline though going from eukaryotes to procaryotes is weirdly just as tricky if not more so. I mean - eukaryotes showed up after life had been on earth for 1 - 1.5 billion years. Procaryotes showed up almost right after the Earth could conceivably supported life at all. That's always struck me as really weird. It also makes me think if we ever find alien life we're probably going to be disappointed.
