Once you watch a few of these, the algo will start feeding you stuff about the 1800's world fairs and the huge buildings they would make in a year and then destroy.
Seems like alot of people believe that some of our big impressive buildings (cathedrals and such) were dug up and not actually built.
I don't really buy it, but the pictures are really impressive.
I've been paying more attention to the Mayan calendar, because it goes way further back in history than any other cultural timeline I know of.
According to the Mayan calendar as of 1500 years ago or so, we're in the "5th age" of humanity, also known as the Fifth Sun. The fourth age ended around 12,000 years ago. Every age ends with a cataclysm and a global reset where humans have to start over from scratch with very few people left worldwide.
As I understand it:
1st Age: The age of "darkness" where there was very little light in the world and giants roamed the planet. Maybe this was before the discovery of fire? This is definitely pre-civilization, when humans were just trying to survive, and perpetually fighting for their lives against big cats / other predators (and probably also giants). Era ended in a cataclysm where humans were basically killed off almost entirely by monsters.
2nd Age: Age of Wind, characterized by perpetually stormy weather. Humans behaved too much like monkeys in this era and it angered the gods. Era ended with a massive hurricane that pretty much killed everyone off, allowing the gods to start over with the more advanced type of human that survived the collapse.
3rd Age: Age of Fire, Humans actually became civilized in this era and began working together. However there were worldwide droughts and ice ages so living was harder than ever. Civilization ended with a firestorm from above, probably a meteor swarm.
4th Age: Age of Water, human civilization re-developed again from scratch and reached greater heights than before. Probably when Atlantis existed, along with the building of the Sphinx and whatever else happened in the antediluvian time period. Age ended with a massive global flood.
5th Age: The current era, humans re-started from scratch yet again about 12,000 years ago and were destined to reach an even higher level than at the end of the 4th Age (which we almost certainly have). This era is supposed to end in massive earthquakes, but only if we stop paying proper respect to the gods.
6th Age: The next age after this one where we start over yet again with just a few people left; is inevitable; not much else to it. Late in the 6th Age people will speculate on how advanced we actually were, much like we speculate about the 4th Age.
Given that each age is characterized by the cataclysm that ended it, it might be possible to suss out the rough time period each of these corresponds to. Like the 4th Age probably ended with Meltwater Pulse 1B.
