Regardless, this is perhaps the smallest piece of a VERY big puzzle.
How does the dna form? How are the left hand amino acids separated from the right hand amino acids? This is an unresolved issue. In all tests, approximately equal amounts of left hand and right hand amino acids are always produced together. There is no known way to separate them. The odds of getting all the left hands separated from the right hands from a purely statistical viewpoint is unreasonable, so until there becomes a simple, natural way to separate the acids, the natural creation of that first dna cell looks bleak.
Secondly, how can the necessity of all that work to partially produce the smallest of the necessities for life support a claim that no intellegence was needed to create life at all?
