Light strikes dust, water and gasses on its way to earth. dust and water particles are much bigger than light's wavelength. but gass particles are smaller so they absorb most of shorter wavelength light i.e. blue. latter these particles radiate blue light everywhere. a view on earth see blue sky as the result. it is called rayleigh scattering.
