Two gases that probably existed in Earth's early atmosphere are ammonia and methane. These gases were likely present in significant quantities before the atmosphere transformed into its current composition.

The gases in Earth's early atmosphere likely came from volcanic activity, outgassing from the Earth's interior, and impacts by comets and asteroids. These processes released gases such as water vapor, carbon dioxide, methane, and ammonia into the atmosphere.
Nitrogen and Oxygen would be 2 of the gases in the atmosphere.
The early Earth's atmosphere was primarily composed of gases released from volcanic activity, such as water vapor, carbon dioxide, nitrogen, and small amounts of methane and ammonia. These gases formed the primitive atmosphere over millions of years as the Earth cooled and solidified.
Earth's early atmosphere was primarily formed from gases released by volcanic eruptions. These gases included water vapor, carbon dioxide, nitrogen, and trace amounts of other gases such as methane and ammonia. Over time, the atmosphere evolved as oxygen levels increased due to the emergence of photosynthetic organisms like cyanobacteria.
The gases in Earth's early atmosphere are inferred to have come primarily from volcanic activity. This outgassing released gases like water vapor, carbon dioxide, nitrogen, and methane. Over time, the composition of the atmosphere changed due to biological processes and the development of photosynthetic organisms.
Most scientists believe that Earth's early Archean atmosphere was formed primarily by gases released from volcanic activity. This included gases such as water vapor, carbon dioxide, nitrogen, and small amounts of methane. These gases were constantly being emitted by volcanic eruptions, shaping the composition of the atmosphere during that time.
