While nobody would deny that we do not yet have a model for the origin of life, you seem to be unaware that there are in fact hypotheses nowadays to account for the development of chirality.
Hypotheses are untested or unverified propositions, which can be made in abundance and will never yield a solution in this case. The 100% chirality required for genetic structures are produced within the cell, another catch22, never naturally which only produces racemic mixtures.
I watched part of an interesting video about this not so long ago, in which the lecturer, who researches in this area, explained he has found that different facets of certain mineral crystals have handedness, which affects the relative strength of adsorption of chiral organic molecules to it. Now adsorption on minerals is one of the processes that has - independently - been proposed for the synthesis of complex biochemically relevant molecules, as it provides a way of stabilising them. This work struck me as very interesting.
Thanks, I am sure it is very interesting and they are desperately seeking a solution, however, it has no relevance to origin of life and will never yield 100% chirality.
The rest of your arguments are typical creationism. What they amount to is the assertion that, because we do not have a scientific model, there can be no scientific model. It is the argument from personal incredulity: "I cannot see how this could have happened naturally; ergo it could not have happened naturally". For instance you speak of "the limitations of naturalistic processes to do the job". I wonder what these "limitations" are and what scientific justification you think they have.
All you have to do is read what forces and processes are being proposed to accomplish the biochemical assembly of increasing levels of complex structures critically necessary for the origin of life -
1. Darwinian processes before life existed, what a joke,
2. Panspermia, which only displaces the issue,
3. Solar radiation, lightening, volcanoes, hydrothermal vents which have no selectivity or regulatory level discretion,
4. There are only 4 known physical forces - gravity, EM, WNF, SNF, none of which is any combination is capable of coding nucleotides, creating bi-directional cell membranes, homochiral amino acids, homopolymerized sugars, metabolic enzymes or proteins, reproducibility or the colocation, coincidence or concentration of critical elements.
Since naturalism is impotent to explain or divulge all that is necessary for origin of life, the logical scientific theory cannot be restricted to purely natural processes. It has nothing to do with "I cannot see," and everything to do with "there does not exist."
As for "shutting down discussion", it is entirely legitimate to call out pseudoscience masquerading as science in order to get religion into school level science teaching. Because that is what the "Intelligent Design" movement is all about. It is social engineering by the American religious right and nothing to do with science at all.
