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.
The atmosphere is made up of lots of different gases. It is impossible to name all of them as there are some that we havent found yet. Hope this helps

The atmosphere of Earth is made up of a mixture of gases, primarily nitrogen (78%) and oxygen (21%). Other gases present in smaller amounts include argon, carbon dioxide, and water vapor.
The early atmosphere changed due to processes such as volcanic activity, which released gases like water vapor, carbon dioxide, and methane. Over time, these gases were modified by the activity of early life forms that produced oxygen through photosynthesis. This resulted in the gradual transformation of the atmosphere into one more similar to what we have today.
Oxygen
Nitrogen and Oxygen.
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.
dioxide
Nitrogen and Oxygen.
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.

Any atmosphere by definition is made of gas.
The atmosphere includes gases like oxygen and carbon dioxide. It would not be accurate to say that it is "made of" only these two gases. In fact, these two gases only make up 21% of the atmosphere. The atmosphere is also made up of many other gases like nitrogen (78%) and rare gases like helium and argon.
The two deadly gases present in Earth's atmosphere four billion years ago were methane and ammonia. These gases were toxic to early organisms and would have made the atmosphere hostile to life as we know it today.
The atmosphere is composed of gases such as nitrogen (78%), oxygen (21%), argon (0.93%), and trace amounts of carbon dioxide, methane, and other gases. Water vapor is also an important component of the atmosphere.
