Nobody really goes about their day thinking about the space above their head.  I mean, yeah, it's there.  And if a noisy bird flies by or say a rainbow appears, yeah, I look up.  But usually, my days are all about looking at eye level or below.  Actually, with Tiny Chumley in the house, it's pretty much always below, unless I am walking somewhere, or talking or looking at big boyfriend.  But my point us, the minutiae of life doesn't require us to be constantly attentive to that space up there.
Except maybe for tiny chumley, who often looks up in hopes that it would rain snackies from heaven. Subtract food from the equation, however, and he's like the rest of us, happily doing whatever he's doing at tiny chumley level, until something happens that makes him ever so aware that something awful just happened, in that space way up there. :)
