Not to be annoying, I'm just pondering but why are clouds white? And, more importantly, why can't you see into space during day, but spaceships can see water and (green) land during day. The atmosphere blocks most of the light coming in, so why would green earth be more visible than other reflections when coming back out. Why don't you see predominately (often red) auroras and other reflections. And I know this may sound stupid, but I just realized that the blue sky isnt high in the sky, its right in front of your face as well. Actually thinking about this I may have answered my own questions, but if you have anything to add, feel free
