> after all, LIFE ITSELF comes from just such an action, so pretty much anything is in play if that is the standard!

That's how an instance of life came about. A very simple, most likely extremely short-lived, not at all efficient form of life. The advancement to Eukaryotes took ~2 billion years from there, and multicellular life took about another billion years. These happened not by random bashing, but selection pressures.

While a solar sail could happen completely randomly, 'life itself' isn't really a good comparison, since that's not really how it happened. At least not any form of life that is really recognizable as life.
