One thing I'm trying to say, and this is important, is that the processes of life we see taking place inside a cell at one time took place outside the confines of a cell. The mechanisms we think of as life is really the condensation of many processes that we see now inside a simple cell that took place in many different areas, places like mica sheets, clay crystals, oceanic ridges (black smokers and cold seeps), lightning flashes, UV radiation, waves crashing on rocky beaches, upwelling of oil (yes oil existed before life), all these things contributed to the process we call life.
Catalysts were literally the catalyst that brought about ever increasing complexity. Catalysts are not just platinum causing hydrogen to react with oxygen and coming out the end of the reaction unchanged. Some catalysts actually produce more catalysts than you had at the start of the process. The catalysts that made more copies of themselves were selected for, these catalysts acted on the organic chemicals being produced by the above mentioned processes, the by products of the catalytic reactions went back into play and were acted on by the mica sheets etc, these chemical loops slowly brought about the increase in complexity. These processes took place over millions of years and trillions of actual reactions each year.
This process acting over time as the chemicals were processed by the two competing processes eventually began to come together in various ways.
I am still working on the details but i see RNA being produced as by the processes of ever increasing complexity of the catalysts, RNA is just a complex catalyst (in my scenario anyway) but lipid bubbles concentrating the chemicals and drifting catalysts being able to more successfully copy themselves inside the lipid bubbles figures big in my idea...
Rigney, it is a bit more complex that a few carbon rocks reproducing but i do see your objection and the complex organics being produced by natural means as shown in the links in my original post is my answer to your objection...
One thing should be added and to me this is the weakest link, I am sure there were natural processes that took place then that are not reproduced by life we have now. i am sure than once life as we know it got started the cells streamlined their reactions quickly and unnecessary reactions were trimmed away fast. i am also sure that both chemosynthesis and photosynthesis both started before there were cells and life as we know it.
