“You can’t sequence stone and minerals.”
They did exactly that, after passing it through numerous chemical baths. The mechanism whereby even collagen could be preserved is unknown at this time, but there was no doubt that they started with a recognizable, hard-as-rock fossil.
Stone/minerals may be made of lot of things but I ain’t ever heard of them being transformed into amino acids no matter what kind of chemical baths are used.
You’ll have to tell me how that works.
