Why is the Night Sky Dark?

Sounds like a pretty simple kids question, does it not? And of course, as adults with faaaaaaah greataaaaaaaaah knowledge know this answer. Well I got my mind blown with this video. Yes the simplistic answer is that the sky is bright in the day because the Sun's radiated energy is absorbed and retransmitted and defused by the atmosphere. But you know what? That is only partially right. I am not going to ruin it for you by giving a spoiler talk. Play the video and then, see if you are not properly struck dumb!
