Game Changer at Abu Hureyra?

Richard Stanley

A new paper in Nature, arguing for a cometary impact at Abu Hureyra in today's Syria, has apparently changed at least legendary overskeptic Michael Shermer's mind:

Even the skeptic Michael Shermer, who famously debated Graham Hancock on the Joe Rogan podcast has tweeted Graham saying:

“Ok Graham, I shall adjust my priors in light of more research like this, and modify my credence about your theory.”
Kudos to @michaelshermer for reconsidering his skepticism in the light of this new evidence —– summarized here: And don't miss @joerogan 961 ( for the full background to Michael's post.

The evidence always spoke for itself for a lot of people, but it’s positive to see him address Graham in a public manner like this.
So what have the scientists discovered? Well, remnants of glass have been found that could only have been created during a high-impact event. Other minerals such as chromium, iron, nickel and others were discovered too, all of which form at temperatures higher than 2,200 degrees, according to a statement from the University of California-Santa Barbara.
The site the discovery was made is known as Abu Hureyra, which was abandoned around 5,000 years ago. ...

Abu Hureyra is relatively close to Göbekli Tepe, Harran, and Urfa/Edessa, and I must wonder if the ancient religious fetish for meteoritic stone may have derived from here.

From the conclusion section of the above-linked Nature paper:

The YDB hypothesis posits multiple airbursts/impacts across at least four continents 1,3,5,8,9,10,11,20,69,73,74,75,76,77,78. These are proposed to have resulted from a one of a series of short-period, active comets known to break up frequently and to shed dozens to thousands of fragments that are 10 to 1000 m in diameter, each capable of producing catastrophic airburst/impacts, as discussed in detail in Napier3,79, Wolbach et al.13,14, and Pino et al.9 (Appendix, Text S8). The largest cometary debris clusters are proposed to be capable of causing thousands of airbursts within a span of minutes across one entire hemisphere of Earth. An encounter with such a million-km-wide debris cluster would be thousands of times more probable than a collision with a 100-km-wide comet or a 10-km asteroid. The YDB hypothesis proposes this mechanism to account for the impact at Abu Hureyra and coeval impacts across >14,000 km of the Northern and Southern Hemispheres.
So they're saying that this is the same airburst responsible for the Carolina Beys, eh?
