Question

If the sun reflects on earth, but the sun is in space, why is space dark?

Answer 1

But in space, there's nothing to reflect the light from the Sun to your eyes - so it looks dark..

Answer 2

The color black usually signals the absence of light. But inside the solar system, space is filled with light.

“Light usually travels straight ahead in a line unless it reflects off of something or is bent by a lens,” explains Geza Gyuk, Director of Astronomy at the Adler Planetarium and a research scientist at the University of Chicago.
