I need to know the secret of the universe...

The same reason the area around the sun looks yellow, actually. Light with more energy (blues) can bounce off air molecules and go in a different direction, so sunlight doesn't just go straight to your eye or else the sky would be black. Red-yellow light travels pretty much straight. You only see those colors scattering when the light goes through a lot of atmosphere, like near the horizon or at sunset or sunrise. It's called Raleigh Scattering (RAW-lee) if you want to impress people.0

Air molecules are small and when sunlight passes through it appears blue coming towards us since blue is a shorter wavelength. Direct sunlight looks "white" to us for example but blue going through air. Hope that helps.
Correct me if I'm wrong but, this is what I learned in astronomy.0
