As viruses show us, the distinction between life and “mere” organic chemistry is far muddier than one might think. When it comes to the first life, and probably even LUCA, even prokaryotes, let alone slime molds are far too advanced. Most likely, we are talking about circles of amino acid reactions in the pores of long-lived alkaline hydrothermal vents (White Smokers).
But even if we just ignore that abiogenesis can and is in fact investigated: The first life simply spontaneously arose in a freak incident of organic chemistry would still be infinitely more plausible and parsimonious than “literally everything we know about natural history, from the entirity of biology to our extensive catalogue of the different layers of the rocks and the ever-different faunas and floras therein, to astrophysics, to even linguistics and history, is wrong, what actually happened is that a supernatural being that is both the platonic abstract deity of Ultimate Perfection and the more traditional abusive God-Father archetype created everything six thousand and twenty-five years ago (taking six days and then taking a break despite being omnipotent), and back then there was no death so obviously, originally everyone was a herbivore no matter how clearly one is adapted to a predatory niche, and all the diverse geological strata and landforms of Earth originated with one single flood that covered the entire Earth (plus any other disaster movie science that I can shoehorn in) over the course of a single year at the times of the Pyramids, and the enormous diversity of life worldwide derives from the survivors of this flood, which consists of one pair of every “kind”, except for “clean” ones that get seven pairs, gathered by an old man, his three sons and their respective wives, all of which contained in a giant wooden box, and also languages all originated in a single catastrophic supernatural event a few generations later, and all of this is detailed in perfect literal accuracy in this one minor ancient orient nation’s mythical epic that on closer examination shows clear signs of being grafted from more than one source and actually starts with two different, mutually exclusive, creation myths, one of them clearly literary, back to back, and which for the rest of its course focuses exclusively on one single family, clearly written to deal with two conflicting founding myths by making them grandfather and grandson (with the linking son/father conspiciously lacking in stories of his own…) while also setting up the founding epic that makes up the rest of the pentalogy.”
(And note that I have limited myself to the basic conceit of Abrahamism, leaving aside all the stuff whatever splinter of that schismatic sect of Hellenic Judaism has been adding to it.)
Sorry for the rambling.
