On the subject of an alternative (non-naturalistic) cause for life on Earth, it is a fact I believe that very little could be said about it. And it's best to avoid wild speculation when a factual vaccuum exists, that's all I'm saying.
Unless it is a scientist who is wildly speculating 😜
But a factual vaccuum does not exist ("an enormous amount of empirical data...suggest that it is impossible for *any* non-living chemical system to escape devolution to enter into the Darwinian world of the living"), and given that "enormous amount of empirical data" an inference that something beyond nature is needed is not illogical or "wild speculation." That doesn't mean other people have to accept that. Everyone is free to disagree. Your position based on naturalism's track record is a valid point. You obviously can reject the "something more than nature is needed" proposal. That's fine by me, and like I said the track record of naturalism is a valid point. But it would be unfair to label an alternative you reject as "wild speculation," when it is a logical inference based on "an enormous amount of empirical data."
Well, I think we've beaten this dead horse...
