You see light on earth (day) because the atmosphere scatters that light, and it is bright enough that it will block out the stars (in most cases). But at night the absence of light is more akin to the natural look of space.
If you live near a city you will be able to see the light pollution of that city at night, and not be able to see stars.
In fact, in LA, an earthquake caused a total blackout of SW CA and 911 was inundated with calls asking if the giant ‘gash’ in the sky caused the earthquake. The truth of it was most people were seeing the milky way for the first time in their lives because all the surrounding light pollution was blocking it out.
