When it comes to our own Solar System, the cosmic story that unfolded was not only spectacular, it was in many ways unexpected. Although they may merge together, collide, interact, and occasionally get hurled into the inner Solar System from gravitational slingshots, they largely remain out beyond Neptune, as a relic from the youngest stages of our Solar System. But the most interesting place of all, for our purposes, is the inner Solar System. And over time, it settled down to form our Earth and Moon as we know them today. At the end of the early stages of our Solar System, it was as promising as it could be for life.
