However, UV would have broken any chemical bonds. Also made double walled microsphere. Perhaps clays formed templates for synthesis of complex proteins. Some say there is not enough organics to make the organic soup on Earth. In the ocean where there is recently solidified lava.
Seawater circulates through it, gets hot and then is vented on the seafloor.
Mix H 2 S, CO, N, and FeS. Cook and get a cascade of changing organic reactions. This is done experimentally, but may not be happening in vents because of the lower concentrations of some of these compounds. We must hypothesize as we really have no evidence. We can hypothesize what it was like. Some workers believe that the earliest organisms were the simple heterotrophs who ate components of the biological soup from which they arose.
