The accepted answer is that it was formed as part of the formation of the earth. The gas and dust complied to form the stars and the planets after the big bang through the force of gravity. Some planets like Jupiter and Saturn are almost all gas, but the planets from Mars inward are rocky ones.
Still part of the planet's composition is gas. At one point the surface was all rocky and then it started cooling. Part of that cooling process was to allow some gases to escape. Along with those gases came liquid water. Early in the planet's history the seas were green with rust, but eventually the iron settled out and became bonded with other materials. Life formed in the sea and then eventually it crept out on land. Plants were the first and when they colonized the planet they absorbed the nitrogen from the ground, and the CO2 from the air. Then they released the waste gas oxygen. Eventually the oxygen supplies became large enough that amphibians could come out onto the land and evolve into the animals that we know of today.
It isn't a question of God's work or not. God could have been the original force behind the big bang; "In the beginning there was void and nothing, then there was a light." That is about the best explanation of the big bang I have come across. Just because the word isn't a few thousand years old and The Bible is wrong doesn't mean that God doesn't exist or didn't have a hand creation. It just meant the bible, written by man and inspired by God, was wrong; or simplified so that primitive man could understand it.
The planet is out gassing to this day. Volcanic vents are releasing complex chemicals into our atmosphere and recreating it day to day. Of course we are also losing some of it daily to space and the plants and animals on the planet are modifying it as well. The action of combining water and chemicals into salt, of wear and erosion all continue to work to modify the atmosphere.

What is a sentence that uses the word weathering correctly?
'' Over the years , weathering changed the way a rock or mountain formed'' .
Why has the nitrogen level in the atmosphere kept constant over time?
The absolute amount of nitrogen in the atmosphere has kept constant over time because it is not a gas that reacts readily with other elements - it is relatively inert. However, the relative level of nitrogen in Earth's atmosphere has changed over time as the atmosphere was "terraformed" by the life evolving on the planet. For instance in the Cretaceous times the atmosphere was much richer in Oxygen (30%) than today (20%) which means that then the %Nitrogen was 70% rather than 80%.
How has the burning of fossil fuels changed the atmosphere?
Burning of fossil fuels has changed the atmosphere by increasing the amount of atmospheric carbon dioxide. Since the beginning of the Industrial Age, the concentration of atmospheric carbon dioxide has increased by over 35 per cent, from the pre-industrial long-term range of 260-280 parts per million (ppm) to the present level of over 380 ppm.
A kind of sedimentary rock formed from plant material over a long period of time is?
The answer is coal, because it is made up of dead plants that are buried, then are chemically changed by microorganisms then compacted over millions of years.

A protective shell over earth is formed by?
Atmosphere
Why did the earth's atmosphere change after it was first formed?
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.
Why has the atmosphere changed?
The atmosphere has changed over time because of the use of chlorofluorocarbons (CFC's) as well as bacterial oxidation changing NH3 into N2 and photosynthesis which made O2 more abundant than CO2.
Has the atmosphere always had the same compisition?
No, it has changed over time. Ex) There was no oxygen when the first organisms evolved.
What components of the earth have changed the least over time?
Components of the earth that changed the least over time include the earth's crust and mantle and the structure of the earth's interior. Other structures that have changed very little include the components of the atmosphere.
What is a sentence that uses the word weathering?
'' Over the years , weathering changed the way a rock or mountain formed'' .
Why is evolution by natural selection called a theory?
Scientists use it to describe how organisms have changed over time.
How are the holes in the ozone layer formed and where do you find them in the atmosphere?
they are formed due to cloroflorocarbonsCFC's and HCFC's procuced by aerosols,fridges,air conditioners,etc. one such hole was over antarctica
How was coal formed over millions of years?
the remains of plant matter is changed into coal over millions of years while the remains of billions of microorganisms and other organisms formed petroleum and natural gas.
What is a sentence that uses the word weathering correctly?
'' Over the years , weathering changed the way a rock or mountain formed'' .
Where in the ozone is the hole located?
The ozone hole is located over the antarctica region of atmosphere. It is formed by natural and man made factors.
Which of these statements is falseThe earth has changed very little over time.The continents are in constant slow motion.Earth's internal heat helps move tectonic plates.The early atmosphere did not contain oxygen?
The earth has changed very little over time.
