    Answer:

    The amount of oxygen in the atmosphere increased.

    Explanation:

    Spontaneous formation of organic molecules occurred on primitive earth since its atmosphere did not have oxygen. The reducing atmosphere allowed chemogenesis. Evolution of photosynthesizing organisms that use water as a source of electron led to the accumulation of oxygen in the atmosphere. Presence of oxygen does not allow the spontaneous formation of organic molecules since the molecules are readily oxidized.
