Yet all around us we see magnificent structures—galaxies, cells, ecosystems, human beings—that have all somehow managed to assemble themselves
Dissipative systems. No more mysterious than the vortex of water flowing down your sink drain.
If the planet was covered with water to start off with, nowhere would molecules be able to concentrate to form life.
Alkaline hydrothermal vents. Perfect environment for life to emerge from geochemistry. I am sure we are on the brink of discovering bacterial life elsewhere. We might have discovered Methanogens on Mars already.
Life from life, etc.
Says who?
