Watch This When You're High - The Fibonacci Sequence

This one comes thanks to @AtTheEndOfTheDay. 

When you see stuff like this it makes it hard to discount a higher power or some thing being behind everything. Is this just totally random?

Also - we really need an explanation on how humans were this smart back in the day before we had any technology whatsoever. It's hard for people and machines to be this precise nowadays with nano-computers, lasers, and you name it. 

Keep the suggestions coming. Keep them classy. No butt stuff.
