Earth's earliest atmosphere lacked significant amounts of oxygen. Instead, it was primarily composed of gases like nitrogen, carbon dioxide, methane, and ammonia. The absence of oxygen was crucial for the development of early life forms, which thrived in anaerobic conditions before the advent of photosynthetic organisms that eventually began to release oxygen into the atmosphere. This transformation marked a significant shift in Earth's environment and allowed for the evolution of aerobic life.
