Verified step by step guidance

Begin by understanding the significance of organic molecules in the context of the evolution of life. Organic molecules, such as amino acids, are fundamental building blocks of life, forming proteins and other essential compounds.

Consider the presence of amino acids in meteorites. This suggests that organic molecules can form in space and be delivered to Earth, potentially contributing to the origin of life.

Evaluate the existence of water on Mars. While water is crucial for life, it is not an organic molecule itself. Therefore, its presence alone does not directly support the role of organic molecules in the evolution of life on Earth.

Examine the discovery of DNA in ancient rocks. DNA is a complex organic molecule essential for life, but finding it in ancient rocks would be more indicative of life having existed rather than the role of organic molecules in the evolution of life.

Consider the formation of ozone in the atmosphere. Ozone is not an organic molecule, and its formation is related to atmospheric processes rather than the evolution of life through organic molecules.
