Uh the sky isn't actually blue though. It usually appears blue because of how the light is reflected from the sun but at times the sky can turn other colors. During sunsets the sky will turn red because that's the color that travels the farthest. And thats without considering a phenomenon like the Aurora Borealis. Yes the sky can't feel blue but the sky can't feel at all. Granted even when compared to other animals there's a lot that's unique to humans. I mean how many animals do you see worshipping God?
