White light from the sun is a mixture of all colors. When it reaches the atmosphere, some of it bounces off of air molecules in random directions. The, shorter wavelength, blue, end of the spectrum bonces more than the longer, red, end. The scientific term for bouncing is refraction.

Due to Rayleigh scattering. Light entering the atmosphere is scattered by water molecules, and blue light is scattered much more than red light, so the sky looks blue and the sun looks red/yellow.
