How would you explain the earth’s atmosphere?

The atmosphere is a thin layer of gases that surrounds the Earth. It seals the planet and protects us from the vacuum of space. It protects us from electromagnetic radiation given off by the Sun and small objects flying through space such as meteoroids.

So it's like a blanket protecting us but it has air hole/patches where sunlight can get through
