Why do some scientist think that areas protected from the atmosphere might a have the atmosphere migt have favored the production of organic compounds on early earth?

Scientists believe that areas protected from the atmosphere, like deep-sea hydrothermal vents or volcanic regions, could have favored the production of organic compounds on early Earth because these environments provided the necessary conditions for chemical reactions to occur. These areas would have had high temperatures, abundant energy sources, and minerals that could catalyze the formation of complex organic molecules. The lack of oxygen in these environments meant that the compounds synthesized could accumulate without being destroyed by oxidation.
