During the first 5-600 million years on Earth the atmosphere was primarily methane,ammonia,and hydrogen,much like other planets in our solar system.How would these conditions favor the formation of biological molecules?

EOxygen, which was scarce in the early Earth's atmosphere, tends to break down organic molecules through oxidation, not reduction. The absence of oxygen would thus favor the formation of complex organic molecules. Additionally, the conditions of high temperature and pressure prevalent in the early Earth would have facilitated many chemical reactions necessary for the formation of biological molecules, contrary to inhibiting them.
