Mostly for the same reason you stay close to the surface of the planet - gravity!
Gases in the Earth's atmosphere stay close to the surface due to the force of gravity acting on them. Gravity pulls the gases towards the center of the planet, keeping them from escaping into space. The mass of the Earth is sufficient to maintain an atmosphere that surrounds the planet.
The Earth's gravity is what keeps the layers of the atmosphere from diffusing into space. The particles of the atmosphere are held close to the surface of the Earth by gravity, creating a stable layer of gases around our planet.
The force of gravity binds the hydrosphere and lower atmosphere to earth.
The atmosphere of Earth is held in place by gravity. Gravity pulls air molecules towards Earth's surface, creating atmospheric pressure that keeps the atmosphere from floating away into space.
Earth is the only planet in our solar system known to have large bodies of liquid water on its surface and a protective atmosphere that allows life to thrive.
Most of Earth's air is found in the troposphere because it is the lowest layer of the atmosphere where gravity compresses and holds the majority of gases close to the planet's surface. The higher layers, such as the stratosphere and mesosphere, contain much less air density compared to the troposphere.
The gravitational pull keeps the Earth's atmosphere close to the surface...
The Earth's atmosphere remains close to its surface due to gravity that keeps the gases from escaping into space. The atmosphere is held in place by the Earth's gravitational force, allowing it to envelop the planet and provide the necessary conditions for life to exist.
The gravitational force between the Earth and the atmosphere holds the atmosphere close, just like it holds you close to the Earth. (ground)

The white planet close to Earth is the Moon. It is Earth's only natural satellite, and its surface appears white due to the reflection of sunlight off its rocky, dust-covered surface.
The atmosphere is above the surface of the Earth because gravity pulls it towards the planet. The atmosphere contains gases that are essential for life, such as oxygen and nitrogen, and it helps regulate the planet's temperature by trapping heat from the sun.
Earth's mass directly impacts its gravitational force, which holds the planet's atmosphere in place. The stronger the gravity, the more likely the planet is to retain its atmosphere. Earth's mass is sufficient to maintain its atmosphere because the gravitational force is strong enough to hold gases close to the surface.
