True, life could have started here, but all the ingredients could have come from off earth. NASA’s Stardust mission collected amino acids, necessary for proteins in RNA/DNA formation, from the tail of a comet.

That and 18.5% of their DNA is ‘foreign’ which is twice as much as any other species. Meaning the derive an exceptionally large amount of their genetic makeup from their environment. Through gene transfer, between retro-viruses and tardigrades.
