The atmosphere is made of gas molecules.
This is the lowest portion of atmosphere - troposphere.
The higher you go above the surface of the earth, the lower the air pressure is, and consequently the less gas molecules your will find within a given volume. Most of the gas molecules in the atmosphere are found below an altitude of 3 kilometers (3000 meters) above sea level.

Bouncing molecules are typical of a gas. Gas can be found pretty much everywhere on the surface of the Earth since we have an atmosphere. So gas molecules are bouncing around in our vicinity, in our rooms, bottles, boxes, you name it.
The molecules of gas are kept in lower atmosphere due to a special force. It is called gravity.
Gas pressure is caused by the molecules of gas striking the walls of a container, or in the case of Earth's atmosphere, the molecules of air hitting the earth. In a vacuum, there are no gas molecules. No molecules, no pressure.

Both oxygen and nitrogen are found in the Earth's atmosphere as diatomic molecules.
