You made the feint, the suggestion about this underwater vent.
You presumably were assuming that raw materials present —> gradual formation of life.
Whereas that is never observed scientifically.
Moreover, it is scientifically improbable i.e. beyond 1:1x10^50 chance. In fact l have no idea how many zeroes the exponent has to make it possible i.e. 1x10^???
Also, l pointed out, you can’t even go from life (marine exoskeltons in chalk) to something relatively simple like the Pathenon. You tacitly acknowledged that would “strain our imafinations”. So if that’s a stretch, then how much more of a stretch would life be, even after abiogenesis. Plus the Miller-Urey experiment was actually an example of, well, blush … intelligent design. And in any case its products, simple molecules “and amino acids” (as if they aren’t mostly simple molecules too, and l don’t think they even isolated specific amino acids but guaranteed it’d be something simple like glycine) which was pretty much bound to happen given the ingredients but anyway … these molecules wouldn’t get you anywhere. To build proteins you’d need enzymes (which are proteins) plus co factors. To build enzymes, you’d need enzymes.
Also note how many mass extinction events (5 apparently) that have occurred. I’m guessing that includes the epoch when the earth was completely covered in ice.
LOTR is more plausible. Theism even more plausible, there’s actual evidence.
