The earth's atmosphere scatters the light from the sun. This is why the entire sky looks bright in the daytime.
On the moon, there is no atmosphere, so the sky is black even when you can see the sun. Everything is lit, but the sky is black.

Light must have something to reflect or refract at. If there are absent, light will scatter through the space. The Atmosphere refracts light and scatters waves with higher energy such as blue light so we see the sky blue. since there's no atmosphere in space, light will not scattered anymore... and all we can see is black.

Nah man, like they all said, the sky is bright because it's bouncing off water vapors in the atmosphere which reflect primarily blue light and tend to absorb other colors.
So when we look up we see a lot of blue light, and that's why the sky is blue, my friend.
On Mars, the sky is red.

The light has to reflect off of something in order to bounce toward our eyes. Then we see the object.

In order for us to see light it has to interact with something. In space there is nothing for light to interact with (..bounce off of)
