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.
- rickycook 8y agoeverything is randomly bashing things together; every human is randomly bashing things together. we are similar, but have billions and billions of tiny differences that make up the specific things about us. everything has selection pressures too: just like life forms exist and thrive in different environments, dust behaves differently at different temperatures and gravities. life as an event, and specific things that happen thereafter are no less “random” than specific chunks of rock/dust in specific configurations

This sliver of dusty ice may have formed in a one-in-a-million random chance, but there's no process that selects for this.
