Summary High $ CO_{2} $ levels are required to warm the primitive earth in the face of decreased solar luminosity. The atmosphere should have had an effective stratospheric cold trap, which would have limited the abiotic production rate of oxygen to relatively low values. Photostimulated oxidation of ferrous iron in the oceans should have been the dominant source of atmospheric $ H_{2} $. Rainout of $ H_{2} $$ O_{2} $ would have kept the atmospheric $ H_{2} $ content high and the $ O_{2} $ content low, even if other sources of $ H_{2} $ were small.
