The gravity of the earth is what holds our atmosphere around us.The gravity is always pulling small amounts of atmosphere out of space.

Since the earth was created, there has been an atmosphere. but the one that was here at that point, is different to the one we know and love. amount of oxygen has changed dramatically over the years, and other gases were in the "air" that aren't here now. Nitrogen amounts have also changed, as well as CO2 among other things.

when the earth was still molten it released many gases, just like hot food releases steam. Also about 17% of earth is carbon that other guy is wrong we got all that carbon from a nearby exploding star. towards the end of a stars life there is no more hydrogen to burn so it starts burning helium into carbon when that is finished there is nothing else it can burn and it shuts down and explodes. earth was showered with tons of carbon which mixed with the oxygen to make carbon dioxide and carbon monoxide also the oxygen mixed with hydrogen to make water vapor which eventually after the earth began to cool condensed and fell to earth creating our oceans. anyway oxygen and CO2 and CO makes up our basic atmosphere.

There is a considerably larger amount of air in your lungs than is let out in a single regular exhale. When you are working, walking, standing, these activities are generally associated with work and do not provide a sense of relaxation.
When you sit down the activity is providing less stress on the body and you let go of more air. Extremely beneficial if you sing to hone your body to use up that excess air

Scientists say Earth got its first atmosphere billions of years ago, when our planet was born.
Scientists think that giant rocks in space smashed together when Earth was forming. These collisions would have caused Earth’s rocks to heat up – and the heating would have led to volcanic eruptions. These eruptions spewed gases – carbon dioxide, nitrogen, and water vapor – the ingredients of Earth’s first atmosphere.

hydrogen.
everything comes from hydrogen
then the intelligence people call god used transmutation to form all the different elements.
hydrogen has one proton and one neutron

It came from natures cycle here on Earth. All is connected. One cannot function without the other.

Plants - the early earth atmosphere contained lots of hydrogen and helium. Over millions of years that escaped from the atmosphere because of it's light weight, and was replaced with carbon dioxide from outgassing rocks, and water vapor, possibly from meteors. As plants began to proliferate about a billion years ago, they fed on carbon dioxide, as they do today, generating oxygen as a byproduct.
