“There are two reasons:
1 Air molecules are smaller than the wavelength of visible light. If a molecule or even a small particle is smaller than the the wavelngth of light, that object is “invisible”. Light cannot interact with things that are smaller than the light’s wavelength.
2. The air molecules can absorb some colors from white light, but not enough to create an effect. What I mean is, molecules of oxygen do absorb some specific wavelengths as the electrons in oxygen jump up and down, but these missing wavelegths are too narrow to make an effect. This is called the “absorption spectrum”

“Air is invisible (at the atmospheric pressure) since the molecules of gases do very weakly interact with visible light)
This means that air does not stop the visible light
If air would be visble, the atmposphere would stop the light from the sun”
