Mainly because Earth has a large enough mass, and therefore a large enough gravity, to keep an atmosphere.
Small objects - and even some fairly large objects - that strike the Earth are heated to incandescence by friction and compression as they enter the Earth's atmosphere. Most such meteorites either explode harmlessly far above the ground or are vaporized entirely.
The atmosphere of Earth contains about 78.08% nitrogen. There has been no other place found that has this nitrogen in abundance, with Mars having only 3% as a remainder of its thin and low-pressure atmosphere.
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.

The planet Earth has a sufficiently large mass, and correspondingly large gravitational field, to enable it to hold on to a large atmosphere.

Some scientists believe it was a large meteor that crashed into the earth disrupting the food resources and proper atmosphere, which led to the large dinosaurs dying off.Some scientists believe it was a large meteor that crashed into the earth disrupting the food resources and proper atmosphere, which led to the large dinosaurs dying off.Some scientists believe it was a large meteor that crashed into the earth disrupting the food resources and proper atmosphere, which led to the large dinosaurs dying off.Some scientists believe it was a large meteor that crashed into the earth disrupting the food resources and proper atmosphere, which led to the large dinosaurs dying off.Some scientists believe it was a large meteor that crashed into the earth disrupting the food resources and proper atmosphere, which led to the large dinosaurs dying off.Some scientists believe it was a large meteor that crashed into the earth disrupting the food resources and proper atmosphere, which led to the large dinosaurs dying off.
The atmosphere naturally moves along with the Earth, as Earth rotates.Note that Earth's rotation may affect large-scale movements (currents) in the atmosphere - this is called Coriolis forces.
The greatest concentration of nitrogen on the Earth is found in its atmosphere. The atmosphere is approximately 78 percent nitrogen.

It doesn't "enter" the atmosphere, it comes from the large mass of the earth which creates a gravitational pull.

The theory is that a moon-sized object, crashed into the earth during it's developmental stages, which then ejected a massive chunk of material from the body of the newly formed earth. This large chunk of planetary debris was then caught in the earth's gravitational field and settled into an orbital path around the earth, forming what we call the moon.
It is found in large amounts in the stars and in the Earth's atmosphere
That's Earth.
