I guess so what? What are the implications? Ryugu is not covered in cellular life. Fermi's Paradox has not been resolved. There's no obvious life anywhere we've landed robots.
Assuming no magic (that is a big assumption), from rocks to life there are like 20 (or 50) steps. We know the first 2 or 3, and have some guess about the last 2 or 3, so there are only 15 (or 35) to find.
This is just a good indicator that our idea of step ¿2? is not totally wrong.
What do you mean by "assuming no magic"? Can you elaborate on why that's a big assumption, because "magic" is usually non-existent.
