Younger Dryas, and the accompanying comet that nearly wiped out all of mankind in flood and fire 13,000 years ago. Every ancient civilization on Earth talks about it.
Thanks for the info. Although the Younger Dryas is fact, the cause is still under investigation. A comet or meteor would make sense, but, especially with the latter, a crater would be evident. As the link below points out, an impact event has evidence, but remains to be proved.
Younger Dryas - Wikipedia
The prevailing theory is that the Younger Dryas was caused by significant reduction or shutdown of the North Atlantic "Conveyor", which circulates warm tropical waters northward, in response to a sudden influx of fresh water from Lake Agassizand deglaciation in North America. Geological evidence for such an event is so far lacking.....A hypothesized Younger Dryas impact event, presumed to have occurred in North America about 12,900 calendar years ago, has been proposed as the mechanism that initiated the Younger Dryas cooling....
Still just a theory, absolutely (as with anything else), but I like the evidence presented, along with all the anecdotal writings of the most ancient writers by way of Gobekli Tepe.
Younger Dryas impact hypothesis - Wikipedia
The evidence claimed for an impact event includes charred carbon-rich layers of soil that have been found at some 50 Clovis sites across the continent. The proponents report that layers contain unusual materials (
nanodiamonds, metallic microspherules, carbon spherules, magnetic
spherules,
iridium,
platinum, charcoal, soot and
fullerenes enriched in
helium-3) that they interpret as evidence of an impact event, at the very bottom of black mats of organic material that they say marks the beginning of the Younger Dryas,
[9][10] and is claimed cannot be explained by volcanic, anthropogenic, and other natural processes.

Recent research has been reported that at
Lake Cuitzeo, in the central Mexican state of
Guanajuato, evidence supporting a modified version of the Younger Dryas impact hypothesis—involving a much smaller, non-cometary impactor—was found in lake bed cores dating to 12,900 BP. The reported evidence included nanodiamonds (including the hexagonal form called
lonsdaleite), carbon spherules, and magnetic spherules. Multiple hypotheses were examined to account for these observations, though none were believed to be terrestrial. Lonsdaleite occurs naturally in asteroids and cosmic dust and as a result of extraterrestrial impacts on Earth. The analysis of the study has not been confirmed or repeated by other researchers.
[11] Lonsdaleite has also been made artificially in laboratories.

A 100-fold spike in the concentration of platinum has also been found in Greenland ice cores, dated to 12,890 BP with 5-year accuracy. This is interpreted as evidence against the Younger Dryas impact hypothesis by the study’s authors, but cited as evidence for the hypothesis by its proponents.

Ancient stone carvings confirm how comet struck Earth in 10,950BC, sparking the rise of civilisations
Ancient stone carvings confirm that a comet struck the Earth around 11,000BC, a devastating event which wiped out woolly mammoths and sparked the rise of civilisations.
Experts at the University of Edinburgh analysed mysterious symbols carved onto stone pillars at
Gobekli Tepe in southern Turkey, to find out if they could be linked to constellations.
The markings suggest that a swarm of comet fragments hit Earth at the exact same time that a mini-ice age struck, changing the entire course of human history.
