    The reason is Rayleigh Scattering.

    Visible light from the sun is Scattered in the Earth's Atmosphere.  Blue Light, having the Shortest wave length is scattered more.

    There is no scientific answer. It is blue due to semantics.

    This is really simple in a complicated way. Read up on Rayleigh scattering, there is your answer.

    The molecules of gases in our atmosphere scatter sunlight; the color scattered the most without being absorbed is blue - that's what we see. When the sun is down, although the same effect is true for starlight, it's so dim that we can't detect the blue. So, the atmosphere appears to be clear to our eye.   

    The effect is called "Rayleigh scattering."

    According to spaceplane.nasa.gov: "Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. ... Also, the surface of Earth has reflected and scattered the light."

    The stratosphere reflects the blue spectrum of light for your eyes to see.  If the stratosphere absorbs all of the light spectrum then you will see it as black.
