Why is the sky blue?

(Most correct yet herein irrelevant answer: Because it doesn't exist.)

If you are thinking something along the lines of the sky reflecting the color of the ocean, you have been duped. On a round planet where you live on the outside (that is, on top of the surface, as opposed to inside or below such as it is on a concave model), there would be tons of parts of the sky that would not be blue if the blue were the product of a reflection. Large parts of the Earth have no ocean anywhere near, and you do not see a brown or a green sky that is the product of a reflection of the ground below.

The answer that the sky is blue because of an ocean mediated reflection is more plausible on a concave earth model (i.e., Earth as a misshapen ball that you live inside of with the universe being a fusion engine at the center of the vessel) as smaller parts of the sky would reflect way larger pieces of the land because the sky would have a much lower circumference that does the surface. Still, even if a concave earth were true, an ocean mediated explanation for the color of the sky would be false.

Although when many of you go to the beach, you see a deep blue ocean in front of you, this is the product of the harm you have done to the ocean. Healthy seas or oceans are not blue, and definitely not deep blue; healthy seas or oceans are green, and when they are very deep, they turn a more aquamarine color, which does have some blue to it but is mostly green. Is the sky above you green?

So why is the sky blue? The answer has two parts, one of which you will understand and the other of which you will not, and I will not explain either. 1) Ozone burns blue, which is why the sky is only blue during the day, not at night and also why it stays blue for a while after the sun has completely disappeared in the horizon. 2) Sky blue is the PRISM coloration of the Fournier Transform, which is how you calibrate and obtain time from distance and distance from time while in fact getting both from sound and proprioception.
