The synthesis of the organic molecules in the primitive atmosphere would have favored because it was reducing and exhibited sources of energy in the form of UV radiation and lightning.
The biggest constituent of the primitive atmosphere was carbon dioxide, succeeded by hydrogen and nitrogen with almost nil oxygen. This atmosphere resulted mainly from the gases discharged due to cooling of the molten plant and at the time of volcanic eruptions.
