The Role of Lightning and Volcanic Activity

Alongside ocean-based theories, some scientists point to lightning strikes and volcanic eruptions as powerful forces in the early chemistry of Earth. Laboratory simulations that mimic the early Earth have shown that electrical discharges, similar to lightning, can transform simple gases into amino acids and other organic molecules. Similarly, volcanic activity released heat and minerals, creating dynamic environments ripe for chemical reactions. These energetic processes may have played a crucial role in assembling the molecular building blocks of life.
