I think you are taking the wrong tack in your approach to this. You keep saying life must arise at the end of an experiment. The thing we can do is work through to dna base pairs arise. If you are then in the right environment for random mixing of these base pairs for millions of years, I do think you'll get microbes. It's a big mistake to say we have to run an experiment that produces living organisms from nothing to say we know how it works. And that likely took millions of years. That feels like an excuse to argue that it can't happen without some external power (not the sun, ha).
