Space is dark even though light is moving through it because there is nothing in it to scatter the light. Light moves through the vacuum without encountering anything to reflect it or scatter it. We can only see the light if it comes toward our eyes.

Have you ever gone diving in the seas ? When you look in to the distance it is dark. It is because there is nothing for the light to reflect from.
Light is everywhere - why we don't see it in space is because there is no where for this light to fall on to and reflect. The earth and other planets illuminate because it reflects the light emitted from the Sun.
Another small example - go to a large dark empty room - may be a hall. Flash a small torch to the distance - you might not see anything - may be the wall - better if the wall if painted black too. Now there is light in the room - but you won't see it because it doesn't reflect off anything. You will see light only if you look directly in to the torch.

Our sky is all lit up because the atmosphere disperses light in every direction. Without an atmosphere, the sky appears dark except if you look directly at a star. Then the appearance of brightness depends on the absolute luminosity of the star and your distance from it.
If you go to the moon and look at the sun, you will be blinded by its brightness but the rest of the sky will be dark.

Light is invisible until it reaches matter. Light will continue to travel until it hits an object. Many of the stars you see at night no longer exist. You are actually looking into the past because the light from some stars has spent millions of years travelling to reach the earth. So by the time the light reaches earth and we see it, it could have really exploded thousands of years ago, but we might not actually see that for another thousand years.

the sun is just another star in space. it is bright to us as it is so close to earth, closer than the other stars. when we are on the side of earth that is facing away from our star the sun, we have the opportunity to see the rest of the stars (which are blotted out in the day by the relative brightness of the sun - but there are still stars in the sky during daylight hours even though we can not see them). If we were on a faraway planet that had one of those other stars as our "sun", this sun that we see every day would be just a speck in the nighttime sky!

It is but there is nothing to reflect the light so it looks dark no atmosphere to defract the light ever. if you go out of your spaceship it is light on one side, the side the sun is hitting and relecting off of and the other is very dark because there is nothing to reflect light back on to the dark side facing away from the sun. Ecept of course you will reflect some light until the sun is eclipsed by the ship.

things look light to us because a source of light such as the sun reflects off items and goes into our eyes to be seen. in space there is nothing to reflect the sunlight back to our eyes so space looks dark in general. of course if one looks directly at the sun it is bright.
