I’m nervous about the idea that life might adapt to conditions in which it cannot originate.
Why this happened on Earth? It is pretty likely for example that life couldn’t originate in an environment like the Sahara desert, but life can adapt and survive there.
I do agree that spores are one of the more plausible scenarios. I don’t know enough to really answer the question, and I’m not sure that anyone does, but your intuition sounds plausible.
There’s barely any life in the Sahara. It looks a lot like spores to me. I want a measure of life that includes speed. Some kind of energy use or maybe cell divisions. I expect the probability of life developing in a place to be proportional to amount of life there after it arrives. Maybe that’s silly; there certainly are exponential effects of molecules arriving the same place at the same time that aren’t relevant to the continuation of life. But if you can rule out this claim, I think your model of the origin of life is too detailed.

I’m not sure what you mean by this.

Do you mean something like the idea that if an environment is too harsh even if life can survive the chance that it will evolve into anything beyond a simple organism is low?
