Because the sun isnt everywere. What spreads around space are light beams from the sun and you wont see them unless you are either directly looking at the sun or they bounce back from a surface or gas cloud.
Space is empty (in general), so theres no way for light to bounce back to your eyes.
If space would be filled with gas it would not be black but visible. Near the sun it would look blue and red farther away. Eventually it would start to "look" infrarred, black for our eyes.

Good question. Space isn't actually dark although as you look out away from the sun it is black. That is because space is a near perfect vacuum, and in this vacuum there is an average of only about 1 or 2 atoms per cubic meter. So once you are outside of Earth's atmosphere there is simply nothing for the sunlight to reflect off of. But, if you were on a spacewalk you would be able to see fine provided you weren't in a shadow or something because the sunlight would reflect off of your suit, tools, spacecraft or anything else in your surroundings. Does this make sense? Basically when you are there you give the light something to reflect off of, while the light waves which don't hit you just go off into infinity leaving an apparent black void.

It isn't dark, the sky is just black. The sky on Earth is blue when it is light because gas molecules scatter blue light, but in the vacuum of space there are not enough gas molecules to scatter enough light to make the whole sky glow, but everything else is brightly lit up. That is why there are no stars in the pictures taken in space; because the camera shutter speed is set for bright daylight lighting.

The sky on Earth is bright because light is scattered by the atmosphere. In space there is no atmosphere, so all light sources are resolved more sharply. You see all stars, including the Sun, as bright lights, but the surrounding space will be dark.

it is because in our atmosphere there is lots of particles and gases, and the light bounces off of that so you see the gases, not the light
in space there is nothing that light can bounce off of so it is dark, except for stars and planets, and some comets

THERE IS NOTHING IN SPACE TO REFLECT THE LIGHT . So the light goes through space with no loss.
