The comment was in reply to a post that said "life was inevitable" in some places. The only thing I'd seen along that line was to the effect that "conditions were such that life was possible." That is a different statement than the first.
Life does come only from preceding life. That is the rule, and there are no known violations of that rule....not that I've ever heard of, anyway.
Actually there has definitely been an absolute minimum of one violation of that rule in the history of the universe. It's just whether the mechanism of the violation was natural or supernatural that is at issue.
