Clovis Europeans Killed By Comet?????

[Gary Svindal]

Thanks for that link, Beags. Although I’ve never read that article, it did put me back on track. I seriously believed this was a newly proposed theory, but it’s the supernova idea of a few years ago repackaged as a comet. When first reading about the supernova theory, I did think such an event would answer a lot of questions about what the hell happened to the Clovis people, and an impact by a huge comet would do the same.

Here is one response to Firestone’s Theory: by Laura Knight-Jadczyk http://www.cassiopaea.com/cassiopaea/adventures243.htm

The evidence that Firestone and Topping discovered is puzzling for a lot of reasons. It would be easy to suggest that they have discovered evidence of ancient nuclear war, and are merely trying to put a "natural spin" on it, but it may not be that simple. We realize that the idea that mankind may have fought nuclear wars in the remote past is not allowed, you see, so we can understand a need to come up with a really scary idea about some sort of cosmic ray bombardment which set off natural uranium and plutonium deposits in the earth. What is most interesting is the fact that we again see that strange number 12,500 B.C.

There are reports of similar evidence from such widely spread regions as India, Ireland, Scotland, France, and Turkey; ancient cities whose brick and stone walls have literally been vitrified, that is, fused together like glass. There is also evidence of vitrification of stone forts and cities. It seems that the only explanation for such anomalies is an atomic blast. Add to that the effects of cyclical cometary strikes, and considering the reported regions that may have been affected, we are really in the soup with trying to date anything! With all the bombs, asteroids, comets, and whatever else flying around at periodic intervals, it seems entirely likely that no radiometric dating method of any kind will straigten out the mess. At best, we can use it as only a guideline.

According to Whipple a comet is a conglomerate of small particles bound together by mainly water ice. A comet can strike at significantly higher speeds than an asteroid, and despite its fragile nature, would logically survive its impact with the earth's atmosphere and strike the surface.
Depending on where the strike occured, and the angle at which the strike took place, large amounts of Terran and cometary debris would be injected into the atmosphere.
Apart from any fire risk, tectites would not be a problem as they would return to the Earth's surface very quickly, the long term danger to Earth would be from aerosols and larger debris that continued to circulate within the atmosphere for much longer periods.
Is there any evidence to support such a chain of events at the end of the Clovis period?
