[DouglasKC]

Evolution is not about the origins of life, that's abiogenesis. Also, there is no way to a priori calculate the probability of life emerging from natural causes because the processes are not completely known. Anybody who claims a probability for the creation of life is pulling the number out of their ass.

Is the short answer "Science doesn't know and can't prove how life began?"

No. In short, evolution isn't concerned with how life began, only how it has changed over time. Those who claim evolution is about the origins of life are either ignorant or liars. I know you have been told about the limits of evolutionary theory. That doesn't put you in the ignorant camp.
