On the way to life , the formation of amino acids on the primordial earth was one of the essential prerequisites. To date, this formation could only be explained assuming a reducing atmosphere, which according to contemporary geochemistry could not have existed. Simulating a neutral primitive CO 2 /N 2 /H 2 O atmosphere above liquid water with frequent electric discharges (see picture) provides a model for the formation of peptides, and thus proteins and ultimately life.
