Verified step by step guidance

Understand the context of Earth's early organic molecule formation, which involves the synthesis of complex organic compounds from simpler inorganic precursors.

Recognize the significance of the Miller-Urey experiment, which simulated early Earth conditions and demonstrated the abiotic synthesis of amino acids, essential building blocks of life, from simple inorganic compounds like water, methane, ammonia, and hydrogen.

Differentiate between processes that contribute to the formation of organic molecules and those that affect atmospheric composition, such as photosynthesis and volcanic eruptions, which are not directly involved in the initial synthesis of organic molecules.

Consider the role of atmospheric conditions, such as the presence of ozone, which could protect organic molecules from harmful UV radiation, but is not directly involved in their initial formation.

Identify the correct statement by focusing on the Miller-Urey experiment, which directly addresses the synthesis of organic molecules from inorganic compounds, a key process in the formation of Earth's early organic molecules.
