	p History is long. Very long. The only thing longer than that is pre-history, and if you start thinking about the lengths of time involved in #[em that] for long enough, your brain will turn into a fine mush and seep out of your ears.
	p So here’s a handy timeline of everything (well, not everything, i am just one person, from one region in the world, and one without any scholastic training in history to boot) to help liquefy your mind. Each date is here listed in three forms. First, there’s the #[b #[a(href="https://en.wikipedia.org/wiki/Gregorian_calendar") Gregorian calendar]] #[+sc('(CE)')], which counts forward from some time about the birth of Jesus of Nazareth, and is by far the most common in use today. A simple ticker of #[b years ago] (ya) helps puts dates into perspective, and the #[b #[a(href="https://en.wikipedia.org/wiki/Attic_calendar") Attic calendar]] starts at the first ancient Olympics (conveniently about the start of European “classical antiquity”).
	p Each event is also handily colour-coded by where in the global theatre it took place:

Far from the lush green world we know today, in this #[+wiki('Hadean') Hadean æon], it is a hellish place, where the ground is broiling lava, asteroids rain from above, and a thick methane sky weighs upon the land.
