You may remember Bill Wurtz from his video history of Japan, which I called "the most entertaining history of anything I have ever seen". I still stand by that, but his new video on the history of the Earth from before the Big Bang — "a long time ago, actually never, also now, nothing is nowhere" — to the present day is just as good. On the development of the ozone layer billions of years ago:
Hey, can we go on land?
NO.
Why?
The Sun is a deadly lazer.
Oh, ok.
Not anymore, there's a blanket.
