3) Going from non-living organic molecules to an organized group of them allowing life. (These have been calculated by legitimate scientists and I'll get the particulars for you.) - > What allows natural selection to drive evolution in any direction is competition. Nothing would drive a group of organic molecules, lying around, to do anything. It would take accidental grouping of the molecules, enzymes and the right amount of heat. And then if one could get to an RNAzyme that replicated itself 100% of the time, the show is on. 
 
> More later when I look up some material that is not at the tip of my brain or fingers. - There is too much material for me to copy as I did today. I'm a self-taught terrible typist. Both authors have a good command of statistics. In "A Case Against Accident and Self-Organization" Dean Overman (1997) quotes odds of a single enzymes needed for life appearing by accident (pg. 60). In "Not by Chance", Lee Spetner, M.D. (1997)gives odds for mutation rates and appearance rates of species, and does not directly discuss the issue of origin of life. - Remember the time for life to appear after the earth cooled enough is about a 400-200 million year period, unless we want to propose that extremophiles started life even earlier. :-) Also natural selection doesn't help. It works in a red of tooth an claw world, or as a plant life tries to crowd out another plant life. Inert inorganic or organic molecules don't compete. Further, all amino acids must be LEFT-HANDED, and all Ribose and Desoxyribose in DNA/RNA is RIGHT-HANDED. Enzymes must be present or the process of combination will take an enormous amount of time and heat. Amino acids in water do not combine, because the combination produces water, so an enzyme is required. (See Shapiro's book.) After all that, I agree with you. If life came by chance it must be tiny fortuitous steps, each step by chance until a functioning RNAzyme is present. Then many differing RNAzymes must appear by the same slow method and somehow begin to work together. A single functional cell has hundreds of protein moledcules, hundreds of amino acids long, and folded to be functional. How did the first folding occur and knew how to adjust itself for function, by chance?
