Why is the sky blue?

.Don't be a Harry *facepalm* but lemme just go on google and find out c:
Ahem *clears throat*
A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.
And that is why the sky is blue v.v unless you're like me and and wear shades bc shady asf
