and the air molecules too are very small i feel them on my skin on my face on my eyelids in my hair against my thighs but most of all on my face the fresh space that touches and touches and touches everything and i move through the sky that reaches all the way to the ground when you come to think of it and its blue here too if you really look for example over at the hills over there thats air molecules from what i hear that color things distantly blue and the forest on the side of that hill is dark with just a shade of blue if you really look and now i know that i see air and thats why the sky is blue .
