It might be similar to the atmosphere on Venus, where the oxygen has combined with surface rocks and as carbon dioxide. On Earth, plants remove carbon dioxide and increase the level of free oxygen that supports animal life. This atmosphere also reduces ultraviolet radiation, which also affects the level of gases.
Earth's atmosphere formed around 4.5 billion years ago, shortly after the planet's formation. The early atmosphere likely consisted of gases such as hydrogen and helium, but has since evolved through volcanic activity and the presence of living organisms to the composition we see today.
Earth's early atmosphere was created by gases released from volcanic activity, such as water vapor, carbon dioxide, nitrogen, and small amounts of methane. Over time, the atmosphere evolved through processes like photosynthesis by early organisms, which contributed oxygen and transformed the composition of the atmosphere to what it is today.
The main gases in Earth's atmosphere today are nitrogen (about 78%) and oxygen (about 21%). Other important gases include argon, carbon dioxide, and trace amounts of water vapor, methane, and ozone.
Oxygen was added to Earth's atmosphere through the process of photosynthesis by early photosynthetic organisms like cyanobacteria. These organisms released oxygen as a byproduct, which accumulated over millions of years and eventually led to the oxygen-rich atmosphere we have today.
Argon is a noble gas and does not react with other elements in the atmosphere, so it has remained relatively constant over time. The initial percentage of argon in the Earth's atmosphere was likely determined by the gases present during the planet's formation. The lack of significant processes that remove or add argon to the atmosphere has helped to maintain its percentage over time.
Almost no oxygen, lots of CO2, still mostly nitrogen.
Today the Earth's atmosphere is being destroyed by all the pollution by cars and power plants.
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.

Yes, before photosynthesis evolved, oxygen was rare in Earth's atmosphere. Early Earth's atmosphere was composed mainly of carbon dioxide, nitrogen, and water vapor. As photosynthesis evolved and became more widespread, oxygen began to accumulate in the atmosphere, leading to the oxygen-rich environment we have today.

The original atmosphere of earth contained primarily ammonia and methane, very similar to the atmosphere on Venus and Jupiter today.

biogeochemistry is used by earths atmosphere
The increased oxygen levels in Earth's atmosphere today compared to earlier in its history are due to the evolution and proliferation of photosynthetic organisms like plants and cyanobacteria. These organisms release oxygen as a byproduct of photosynthesis, gradually increasing its concentration in the atmosphere over millions of years.
