"What is it about the simplest living things that needs to be explained? For example, all self-reproducing (‘living’) cells have a set of very complex chemical units called tRNAs (‘transfer RNAs’). There must be at least one unique tRNA for each of the ~20 amino acids that make up proteins.
These tRNAs are essential for the manufacture of all proteins since the cell’s machinery uses them to interpret, from the DNA code, which amino acid is to be used at each position of a protein.
But these are just a small component of the genetic equipment needed! Dr. Truman researched the biochemical source of tRNAs and noted that their manufacture was coded for on DNA and they must be extracted by special proteins.
But these proteins could only exist if functional tRNAs were already available to help decode instructions for their manufacture.
He concluded that tRNAs and proteins could never arise by any natural (evolutionary) process."
