Why Is There No Light In Space?

Space within our solar system looks dark despite having a giant burning star, Sun. Irrespective of day or night, the sky on the moon would always look dark if you were to stand on it and see. As you may have learned in school, our Earth is surrounded by a thick layer of the atmosphere. When sun rays hit the atmospheric layer, the light reflects, and photons scatter everywhere causing the illusion of blue sky. Hence, it's not the Sun, but our wonderful atmosphere that's responsible for bright days on Earth.
