Based on modern geochemistry's view of the atmospheric and geological conditions on the primordial Earth ∼3.8–4 billion years ago, the most realistic scenario for the formation of amino acids and peptides in chemical evolution is discussed, including possible reasons for sequence preferences in early proteins and for biohomochirality. Arguments for a peptide/protein world as primary origin of life, preceding RNA/DNA-based evolution, are presented.
