Oceanic thermal vents is the highest probability origin of life on earth.

Those thermal vents basically set up an electrical energy ion channel at the edges of the vent streams - at the border between the vented material and the surrounding salt water.

Those conditions are replicated inside basically every living cell known to biology, excluding viruses and phages.

I agree, but also I’m willing to entertain the idea of a virus/phage extremophile hitching a ride on the interior of a comet and then hitting earth and finding a “perfect host”.
