Another Fun Fact: the Appalachian mountains formed before sharks existed, the rings of Saturn existed, and before bones existed.

And the north star, Polaris, is a fraction the age of sharks at only 50-70 Mya (it's a trinary star system but the other two stars are much dimmer and not visible to the eye)

I love this fact.

Also: life on earth is almost as old as the universe itself, within the same order of magnitude. 4.1 GYA (billion years ago) vs 13.8 GYA. We're old and intelligence is hard.
