  While it's unlikely this really moves the needle in terms of other life in the solar system (which seems like a pretty hard "no" to me as a lay person), it perhaps does have an impact on "rest if the galaxy".

  Of course the ingredients are "necessary but not sufficient ". However being "abundant" increases the chance of them being present when the other necessary conditions are met.

  Given that the Ryugu sample was contaminated, how confident are we that these samples werent also contaminated?

  The theory of physicochemist Arrhenius strongly suggests that we are the descendants of life that arrived on Earth carried by spores from space.
