Abiogenesis is impossible

so, i put this out there - "one problem for undirected spontaneous interactions from a prebiotic compound is that the dna complimentary 2 strands that form the double helix construction cannot bind with each other unless all the building blocks (nucleotides) are of the same handedness (here, all 19 are left handed). nature and lab experiments have shown nonbiological processes produce molecules in essentially 50% (even distribution of right, left) which corresponds to randomness, whereas encoded information (building instructions) directs handedness from the get-go." - knowing that the evolution microbiologists have given up explaining it; but still, i thought someone on this board would tell how it's done by unidirectional processes. again, two need to be explained: double helix design and construction, and the 19 nucleotides all being one-handed (whereas experimentally it comes up randomly around 50%.).
