so we can breathe. Like oxygen is a gas and we breathe it in because we need it to live. To protect us also. To help break down meteors.
Extra answer:
The atomosphere is made up of 70% nitrogen, 28% oxygen, and 2% other gasses like helium.
The atmosphere of Mars is mostly composed of carbon dioxide (about 95.3%), with small amounts of nitrogen (2.7%), argon (1.6%), and traces of oxygen and water vapor. Mars has a very thin atmosphere compared to Earth.
Earth is the only one we know of so far :)
Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and halons are the main gases that destroy the ozone layer. These gases are released from human activities such as refrigeration, air conditioning, and aerosol propellants, and they break down ozone molecules in the stratosphere, which protects life on Earth from harmful ultraviolet radiation.
Carbon dioxide. In its gas form, it is one of the most important gases to have in the air. CO2 gives plants the ability to live, and it holds some of the Sun's heat in and around people . . . otherwise, they would freeze when the Earth's surface is turned away from the Sun's warming rays. For this reason, CO2 is one of the greenhouse gases, along with water vapor and methane.
One example of a natural process occurring inside Earth without human input is volcanic eruptions. This is caused by the movement of molten rock beneath the Earth's surface, leading to pressure build-up and the release of magma, gases, and ash through a volcano. These eruptions can have significant impacts on the surrounding environment and climate.

Earth.
Oxygen makes up 20.95% of the air surrounding Earth (that is almost 25%).
Oxygen makes up close to one quarter of the air surrounding Earth.

One important effect of the rise in the level of greenhouse gases is global warming. Greenhouse gases trap heat in the Earth's atmosphere, causing the planet's average temperature to increase. This can lead to various consequences such as rising sea levels, more frequent and severe weather events, and disruptions to ecosystems.
one is the dirt while the other is surrounding the Earth's core
Four systems found on Earth are the atmosphere (the layer of gases surrounding the planet), the hydrosphere (all the water on Earth), the biosphere (the combined realms of living organisms), and the geosphere (the solid earth, including rocks, minerals, and landforms). Each of these systems interact and influence one another in various ways.
The three most important gases for life... I would say: oxygen, carbon dioxide and the last one, hydrogen

earth gases are that naturaly formed on earth eg. oxygen and the one in are gas boilers that people pump out of the ground is methane.
Well in terms of Global Warming, the burning of fossil fuels (gas for cars is one) releases more greenhouse gases, which mean there are more greenhouse gases in the atmosphere. These gases reflect sunlight BACK towards earth, keeping it warm. So the more greenhouse gases means the earth is warmer.
