They also discuss where in our solar system, and beyond, similar processes may have resulted in the origin of extraterrestrial life. It's something very primitive. But that was the challenge-the fact that some groups of molecules could cling to rocks and not be washed away, which would be the very primitive beginning of something that could lead to something more complex. It's that sort of reasoning that we follow throughout the book. Even at present there is an incredible diversity of life that can survive in all kinds of environments.
Life is resourceful.
