can we see the sky?

We see sky blue because of the concentration of air and the water molecules, I believe. In the school they have taught us the reason of the sky color, and I remember it like I wrote in earlier. Although I am not 100 percent sure, I think that this is the reason of us seeing the sky. The sight range is till we can see, although we cannot distinguish things so clearly. We see stars, and we know that stars are very far away, so it means that our sight range is very long. I hope I was useful. Cheers!

we can see it but only with limited distance. beyond that, i dont know. nice question, really interesting.
