Life as we know it is too complex to have originated in its present form. Nucleic acids and proteins and most organic molecules necessary for life are too complex to have originated in the primitive atmosphere even if the conditions were favorable.We need to find something that is capable of growing, replicating (not perfectly), and providing a substrate for the formation of molecules necessary for life as we know it today. What could possibly do that?
Ah yes, crystals of clay! Clay is abundant. It grows and replicates but not perfectly thus allowing for irregularities to accumulate. These crystals with irregularities could then provide a surface that brought molecules together in close proximity so that they could interact and produce the organic molecules needed for life. Eventually, the secondary organisms that resulted from this process achieved a certain complexity that gave rise to life as we know it.
Ironic!
