why are the sky blue

The sky is blue because the air scatters blue light from the Sun across the sky and down to our eyes.

Nitrogen molecules scatter blue light more than they do the other colors. So a little bit of blue light bounces around in the sky and then enters our eyes. That makes the sky look blue.
