13,000 years ago, something very bad seems to have occurred, leaving a layer of carbon suggesting dramatic fires. But for much of the last decade, scientists inspecting the remnants of the village have debated what happened, unable to decide whether the carbon formed during an airburst or during more mundane fires among the thatched huts.
So Moore decided to reexamine the glass in more detail. His analysis of the glass composition matched a 2012 finding claiming an airburst had destroyed Abu Hureyra, suggesting that the villagers' bucolic lifestyle ended suddenly when one or more fragments from a passing comet exploded in the air nearby.
Moore and his colleagues heated fragments of the glass in a laboratory furnace until they had fully melted, which occurred at 2,400 F (1,300 C), establishing a lower limit for the temperature the spheroids had originally been exposed to. But it took higher temperatures for the quartz and other particles on the exterior to melt.
The researchers also compared the Abu Hureyra material with glass melted at other prehistoric impact sites on Earth and found many similarities. The wealth of meltglass dating to roughly the same timeframe suggests to researchers that thousands of pieces of debris shed from a comet slammed into Earth's atmosphere 12,800 years ago, impacting more than 40 sites across North America and Europe.
The new findings by Moore's team match a 2007 hypothesis that Earth experienced several multi-continental airbursts. Since an individual comet or asteroid large enough to cause such widespread destruction is unlikely, the researchers suspect the disparate impacts were possibly caused by cometary debris.

and thats another question far from resolved isnt it.
The site of Zoar remained visible and was recognized as such for long after; the rest of the sites are likely submerged, due to the Valley of Siddim having become the Salt Sea / Dead Sea.

There are no green mammals...
Gee, too bad nothing like this happens today, like, say, over Tehran...
Am I the only one picturing shots of Fireball whiskey?
This is part of the same event that killed off all the mega fauna. Most of the impact was in North America on the Laurentide Ice Sheet.
The event is believed to have lasted for 100 years in a cycle as the the Earth passed through the debris of a broken up 100 mile diameter comet. All of North America burned in massive firestorms that left a over foot thick “black mat” of burned vegetation.
Other common evidence is to be found in the Carolina Bays and the Nebraska Rainwater Basins. There are many peer reviewed papers on these connecting them to this event. Both were caused by large chunks of ice thrown up into the stratosphere landing and shattering sending razor sharp ice shards in all directions slicing all things in their paths.
This titanic catastrophe began the Younger Dryas Period of 1000 years of very cold temperatures causing the once melting Ice Cap to regrow. This period is believed to have ended when the Earth encountered more mile diameter chucks.
This cycle continues today as the Earth passes through the Taurid meteor shower in the fall. Hopefully all the large chucks are gone now.
Bada Bing, Bada BURN
ROTF!
AIRBORNE!
Death from above!
The Earth has been around a long long time. There could easily have been another fully advanced civilization wiped out by their own folly or a celestial event of great magnitude.
Wow. Sounds like that was a real bad time to be alive.
Might this be the same event that created the Carolina Bays?
Thank you. I knew I was off on at least the timing.
The Carolina Bays and Younger Dyas periods are “energetically discussed” these days. I’m not sure that either can be discussed dispassionately today.

De nada.
I wholeheartedly agree.
Yes there are! Kirk porked one on Star Trek.
Thanks desertfreedom765, in before I got here.

First thing I thought of, LOL
