You can't have light at night , and have the stars to .
To create an atmosphere that diffuses light , you need water in the air .
Therefore the stars would be hidden .
Cloudy nights reflect and diffuse light back from our own lights , and do the same for the aurora borealis .
So starry starry night, your beautiful but on long winter nights we could light everything up just by aiming lights upwards to clouds .
