That's neither a fair nor an accurate description of a proteinoid microsphere.

That's just the point. Proteinoids are real proteins (listed in Chemical
Abstracts under Protein, subheading Thermal) because they are polymers of
amino acids linked by the peptide bond, but they are not synthesized via DNA.

Except that experimental evidence demonstrates the exact opposite. And there
is almost no experimental evidence to support a "DNA first" scenario. Even
Crick has admitted that DNA did not come first.
