Oxygen, carbon dioxide, nitrogen, and water vapor are essential substances in the atmosphere for life on Earth. These gases provide the necessary components for respiration, photosynthesis, and the water cycle, which are vital processes for sustaining life on our planet.
It is where life began on Earth. It is the majority substance in life on Earth.

no, in fact they are necessary for life.

Argon is the least necessary component of air for life on Earth. It is an inert gas that does not participate in biological processes and is not essential for human respiration.
It exists in nature as a solid, liquid and gas; it freezes from the top (thus leaving the deep waters of rivers and lakes liquid); it dissolves virtually every other substance on Earth, including those necessary for plant and animal life.
The three states of a substance essential for life on Earth are solid, liquid, and gas. These states determine how matter behaves and interacts with its environment, allowing for processes like nutrient absorption, transportation, and energy transfer within living organisms.

Nothing harmful. Carbon dioxide, which comes from car exhaust is a naturally occurring substance emitted from the earth itself through volcanoes . It is a necessary substance for life on earth. Humans exhale carbon dioxide, and plants take it in for their survival, emitting oxygen in return. So I guess you could say you are feeding plant life when driving your car! Just don't you breath it in, especially in a confined area!
There is a water cycle because it is necessary to sustain life on Earth.
Water is the necessary device for the survival of life in this earth
