I can't believe all these joke answers. It's because on a clear cloudless day-time sky is blue when molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.
The white light from the sun is a mixture of all colours of the rainbow. This was demonstrated by Isaac Newton, who used a prism to separate the different colours and so form a spectrum. The colours of light are distinguished by their different wavelengths. The visible part of the spectrum ranges from red light with a wavelength of about 720 nm, to violet with a wavelength of about 380 nm, with orange, yellow, green, blue and indigo between. The three different types of colour receptors in the retina of the human eye respond most strongly to red, green and blue wavelengths, giving us our colour vision.
It has to due with light refraction and how we see it. It has nothing to do with a God. We should only use a GOD as an excuse for the things we havent figured out and/or proven. All else seems to have some scientific evidence behind it.
sky rhymes with pie, pie is food, bananas are food, bananas grow on trees, trees have bark, dogs bark, dogs have fur, coconuts have fur, coconuts grow on coconut trees, coconut trees are found near the ocean, the ocean is blue and the sky is too
