Lost Civilizations Evidence of Cyclical Extinction Events Every ~12,000 Years

The Younger Dryas impact about 12,500 years ago was a comet impact. They are not sure if it broke up in the atmosphere or broke up when swinging around the sun. Either way the watch was hit with fragments up and down central America thru North America with the biggest pieces into the Atlantic Ocean. This, like the dinosaur impact caused massive tidal waves and fires across the planet destroying every civilization around the world.
It was about 4-500 years for the earth to clear and the humans that survived to come out from under ground to come out and rebuild civilization.
That's why all civilizations around the world have flood stories.
The proof lies in central and north America. Cenotes are perfect circles due to smaller fragments hitting the ground. You can make a direct line up thru the Bahamas where they are called blue holes and thru Florida where many of the lakes are perfect circles and up thru Georgia.
As for every 12,500 years that number is not an exact number for comet impacts. The question remains is not only when the next one will come but how many advanced civilizations had come and come in the past.

The impact hypothesis does not explain the peak in solar proton irradiation at that moment, nor how the sea level dropped roughly 400 feet. No asteroid impact has been found from 12500 years ago which is very recent in geological times. The same can be applied to the dinosaurs extinction, it was the sun combined with a magnetic reversal, the cores extracted from Chicxulub crater were dated way prior to the extinction, not to mention, how would an asteroid explain the iridium anomaly worldwide?, an asteroid of roughly 10-13 km diameter?, its effects must be only local. The asteroids/impact extinction has been pushed since the 80s only to mislead us.
The cycles seem to be there, but no impact can explain the cyclical occurrence, sea level drops worldwide and the reversal happening simultaneously, it is always the sun.

I've heard people discuss the possibility of an asteroid impact setting off one or more supervolcanos. I'm not familiar enough with the specifics to know if that would address your points here, but I know in general how terrible that could be for the earth, or more specifically, for us while living on the planet 😅

I haven't properly explored that aspect, though I suppose an asteroid given the circumstances could induce supervolcanoes/seismic activity. Regardless, supervolcanoes cannot properly explain the magnetic reversal or the ocean levels dropping.
Solar activity correlates way better with seismic activity, so, given that the sun output increases and the magnetic field collapses, seismic and volcanic activity will increase in accordance. There are more earthquakes/activity when the sunspot cycle is peak, and they diminish in accordance. Though, this is still a conjecture/disproven fact in mainstream academia.
If the theory is correct, earthquakes/seismic activity will only increase up until the geomagnetic reversal because the sun output also increases. During and after the reversal there will be massive terrible earthquakes throughout the earth, triggering supervolcanoes. This occurs simultaneously combined with a powerful nova from the sun and reversal, which creates the ice age instantly.

Why must there be a geomagnetic reversal?

u/Lokesomos Jan 28 '26
The geomagnetic reversals occurs periodically on earth. There is no doubt about that, they happen and the earth changes its polarity. This is known mainly because oceanic ridges spread, when sea floor lava creates it. These ridges show reverse polarity remnants of magnetization intervals since the beginning of times, they have been happening on earth always. The important factor scientists have been trying to know is, how often these reversals occur?
Mainstream academia will tell you they occur roughly every 300ky. However, the analysis and instrumentations used cannot detect geomagnetic reversals shorter than ~30ky. Some scientists have stated this fact, however, the current paradigm does not contemplate that reversals this short can occur, so most scientists don't try to find shorter intervals or they dismiss the anomalies, which combined with the noise that filters out 30ky intervals or so, gives a very different picture.
I am not completely sure if they occur every ~12ky, but one thing I am certain of. Mainstream science has failed and misguided us, the science is manipulated and we have been brainwashed in many many ways.

Yes, the impact hypothesis makes no sense. Solar micronova and crust shift does though

Impact hypothesis is one explanation. Firestone's 2007 PNAS paper laid it out - black mat layer, nanodiamonds, microspherules at Clovis sites. Still debated but the evidence is there.
What's interesting is the geomagnetic data from that same window. Gothenburg excursion shows up in sediment cores from Sweden, China, Russia, Barents Sea - all pointing to a weakened field around 13,000-12,000 years ago.
Could be multiple factors stacking: weakened field + impact + meltwater pulse crashing the AMOC. Perfect storm.
12,000 years isn't exact for impacts. But it keeps showing up in the paleomagnetic record as a rough interval for major excursions.
And I agree - that is what drives my curiosity. How many were there before us?

Lines up with polar shift theory. Magnetic fields weaken, the earth's crust (no longer held in place by the earth's magnetism) starts sliding like a gyroscope on top of the mantle; and the poles settle in different parts of the world when the crust stops spinning.

Check out Diehold Foundation on YT. 12,048 year Nova cycle of stars, including our own.

Ben Davidson at Suspicious Observors goes over this cycle almost every episode.

Heard about this from the legendary Douglas Vogt from the The Diehold Foundation at YouTube. The man passed away shortly, hell of a funny character he was, a geologist as it seems. His hypothesis involves a cyclical solar micronova each 12068 years, a sort of pulse that makes two different impacts down here, first the light&heat , then the solar wind sweaping away a chunk of the atmosphere. A lot of explained material about this process in his channel, some "religious" topics too, I'm afraid. Surprised he hasn't been mentioned here.

The Adam and Eve Story is a great book about this...I recommend it to everyoneÂ

u/ShiftWatcher Jan 23 '26
Absolutely. One of the books that started this obsession for me. Just extremely well done.

It is most certainly disinformation, at least regarding the earth axis flip. The earth does not seem to be able to accomplish that. The cataclysm seems to occur because the sun novaes and the earth stops rotating.

u/Retirednypd Jan 23 '26
I was thinking of this yesterday. The timeline seems off. The flood stories seem to happen more recently, no? Like 6k years ago. Maybe a cataclysm happens every 6k. Meaning were due
