Part of my brain knows it's caused by the diffusion of light entering our atmosphere. The molecules which make up our planet's air slightly inhibit the passage of one particular wave length of light as it moves through. This slows it enough so the human eye can register the wavelength as a distinct input known as colour and defined as blue.
