I honestly don't know why the sky is blue. My lucky guess would be that it has something to do with the sun and oceans, or it has something to do with outer space. I have not learned about why the sky is blue. If I have, I think I would have remembered because it it something useful to remember. I think the sky's blueness has something to do with the sun because it is like a color thing. I think something reflects off of it which is why it is blue. I'm pretty sure it has something to deal with outer space. I have seen in movies that the higher you go up in the atmosphere, the darker it gets. So it's light blue now, but when you go higher, it gets darker.
I really don't know why the sky is blue. But hopefully, I get to learn in class all about it. I think it would be interesting to learn about it because I dislike not knowing about these things. Some people are saying God painted the sky blue. I think that is true in a religious perspective.
