How did chemisty and oceans produce this?

Formation of Planetary Atmospheres:

There are hence two keys to the evolution of planetary atmospheres:

After condensation of water vapor produced the earth's oceans, thus sweeping out the carbon dioxide and locking it up into rocks, our atmosphere was mostly nitrogen. Currently, our atmosphere is 72% nitrogen and 28% oxygen (everything else like H2 and CO2 exists only in trace amounts). So where did the oxygen come from?

So now let's make some life over the next billion years or so:

Amino Acids now loosely mixed in the oceans

So now we have some amino acids (monomers) loosely mixed in the oceans. Liquid medium is important:

Next goal is to combine monomers into Polymers (peptide chains)
