Science Solution - Why is the Sky Blue?

     There are three reasons why I think that the sky is blue. One reason is of all the molecules or elements in space that cause the sky to be blue when light shines on it. When lights from the sun and stars shine on the sky it may reflect blue light. Therefore, the sky absorbs all light. The sky is like a thing and absorbs light and reflect light. Another reason is that the sky reflects water on Earth and that made it the way it is. Since the water is like a mirror it reflects the sky and then the sky changes color. 
     Another reason may be that every organisms' eye can only see the sky this way. Therefore, the sky doesn't have a change. Our eyes just see and function like that. These are three reasons why I think that the sky is blue. It can be because of the the molecules that reflect the blue light, reflection of water, or our own eyesight.
