Why do you have night time when it is dark and you cannot see the sun?

In space there is no light, except that which comes from stars, like our sun. So a more apt question might be "why do we have light?".
Our sun, like other stars, is in a constant state of nuclear fusion, which creates immense amounts of energy. Light is how we percieve part of this energy.
The earth is orbiting the sun, and as it does so, it spins. This spin is what causes the phenomenom of 'day' and 'night'. As the earth spins, one part is facing the sun (daytime) while the other faces away (night time), into the blackness of space--remember, there is no light except from the sun and stars.

Some regions are dark because there are vast distances between celestial bodies and only they only emit radiation under special circumstances.

∙ 13y agobecause the earth spins at a 23.5 degree angle and rotates around the orbit causing daytime/nighttime, also, if we dont have daytime/nighttime, we wont have seasons nor sunshine/night, and you dont want that,do you?

∙ 14y agoYour eyes respond to light. When light enters your eyes, a signal goes to your brain, and you know that light is entering your eyes. When light doesn't enter your eyes, no signal goes to your brain, and you know that no light is entering your eyes. When no light is entering your eyes, it is because of either one or both of the following reasons: 1). There is no light around where you are. We call this "darkness". 2). Your eyes are closed.
