If this is coming from metals in these rocks forming electrochmical cells, they should’ve corroded away long time ago. Maybe there’s some unknown process that recovers metallic elements back from salts? Maybe some bacteria? Even if, then why? It costs a lot of energy to do this.
It was grabbing a toehold even when our world was a literal hellscape.
Actually this makes sense in the context of autocatalytic sets hypothesis - you’d need large variety of inorganic compounds and a strong energy gradient to kickstart a metabolism.
There’s great video on the subject from Sabine Hossenfelder https://www.youtube.com/watch?v=7yOiZLHDV3U

Wonderful, you have bribed critics reviews, and botted audience score
