The Earth is the third planet from the Sun.
The Sun appears to set because the Earth rotates, turning one side of the Earth away from the Sun for a period we call "night"
Assuming you mean "why": if the Sun appears to set, that is the result of Earth's rotation.

The Sun doesn't really rise and set; the Sun sits there in the center of our solar system, unmoving. It is the Earth spinning - and us with it - that makes the Sun appear to rise in the East and set in the west.

It depends where you are on Earth.
