The original atmosphere contained only nitrogen, carbon monoxide, carbon dioxide, methane, and water vapor.
Today's atmosphere contains 78% nitrogen, 21% oxygen, 1% shared between argon, carbon dioxide, helium, methane, ammonia, and neon.
Perhaps if we look at how the Earth's atmosphere compares with the atmospheres of Venus and Mars, you will come up with some ideas about how atmosphere and temperature can be brought into better control.
The primitive atmosphere was mainly composed of CO2. However, with the emergence of life, this CO2 was reduced in photosynthesis and increased Oxygen. Now our atmosphere is mainly composed of Nitrogen.
As opposed to today's atmosphere, the Earth's early atmosphere would have been quite impossible for human life to thrive in. Today the atmosphere consists primarily of Nitrogen, Oxygen, and Carbon Dioxide, but early Earth's first atmosphere was probably made of Hydrogen and Helium.
Earth's atmosphere contains a variety of gases, including nitrogen, oxygen, argon, and carbon dioxide that have allowed and continue to allow our forms of life to continue to function and develop.
Earth's atmosphere is unusual in that it contains an abundance of free oxygen. This element so readily combines with other elements that its presence in an atmosphere is considered an excellent signal for photosynthetic life. Venus and Titan (Saturn's largest moon) both have atmospheres much denser than ours. The atmosphere of Mars is far less dense--only one thousandth of the pressure of ours at sea level. The Martian atmosphere could not support humans, but it could support other earthly life forms.
The primitive atmosphere was filled with hydrogen and had very little oxygen. It also contained ammonia and methane. This type of gas could not have supported human life.

Hydrogen,mathane ammonia and water vapor.
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
no, they differ in heat and weather

Yes. The air is never clean.
free oxygen
There was an ozone atmosphere on primitive Earth, but not an ozone layer which was formed further on. The primitive atmosphere on the surface of the Earth mostly composed by ozone was pushed upwards by the oxygen formed by dead organisms. That primitive ozone atmosphere on the surface of the Earth protected the forming microorganisms from the UV radiation. JamesWest09
Earth has oxygen they don't.

earth has people in it's atmosphere
