Thanks BenLurkin.
...16 scientists in fields ranging from archaeology to crystallography to physics, who have offered counterevidence to the existence of such a collision.
IOW, they have no answer for the extraterrestrial crud found embedded in mammoth tusks, or the black mat, or anything substantially related to the thesis.

Just adding to the catalog, not sending a general distribution.

To all -- please ping me to other topics which are appropriate for the GGG list.

A meteor (high density material, rock and/or metal) would do significant damage to an ice sheet, to be frozen over and plowed flat by the same ice sheet.

However, the impact of a comet (lower density material) on an ice sheet might be different, especially if it broke up before it hit.

What astronomers stubbornly refuse to acknowledge is the static electrical charge differential between comets and meteors and planet Earth. They think that the Solar System is homgeneously electrically neutral while calling the Solar Electric Current the “Solar Wind” and the Van Allen plasma sheaths- “belts”. The Solar System is alive with electrical phenomena. 99% of all matter in the Universe is in the plasma state- ionized and electrically and, more importantly, magnetically, active. That’s what those pretty “nebulas” are made of and is what astronomers describe as “filaments” which stretch between galaxies as well as comprising their “arms”. These ubuquitous “filaments” are in reality plasma Birkland Currents.

It doesn’t take a rocket scientist to see that an approaching meteor can discharge violently at some point in the Earth’s atmosphere and shatter itself into much smaller components, as the evidence suggests at Tsunguska and as we witnessed at Chelayabinsk. Comets can also break apart (they are not “dirty snowballs”, but rocks just like meteors) and become a freight train such as Shoemaker-Levy 9, which can become a plasma torch creating a swath of plasma furnace temperatures burning everything and melting mountains like candle wax. http://sites.google.com/site/dragonstormproject/

Astronomers cringe at the possibility of one day having to admit that we live in a cosmic shooting gallery because our only defense, at present, is our Cold War nuclear ICBM arsenal, which would then take on the property of savant technology and the elevation of men such as Edward Teller to guardian angel status.

"If man could wipe out mega-fauna as soon as they arrived, then why are there any animals in Africa where man was present many many years before in the Americas."

I think Africa is a great counter-argument to the over-kill hypothesis; especially when you consider the survival of large animals in Africa, like the elephant (similar is size to the mammoth and mastodon), despite facing constant hunting pressure from humans for tens of thousands of years longer than the mega-fauna did in the New World.

I know that one of the theories is that animals in the New World didn't recognize humans as a threat and pretty much allowed themselves to be easily wiped out, but it seems to me that the devastation was too wide-spread and included too many species. The species that didn't go extinct figured out that humans were a threat quickly enough.

In Firestone’s book, there is evidence that Lake Michigan was formed by two or three boloid strikes. Also, what about the directionality of the Carolina Bays?

To believe man was responsible you would have to believe that small groups of hunter-gatherers in N. America were responsible for the destruction of mammoths, mastodons, giant bison, horses, camels, harrington's mt. goat, american cheetahs, american lions, american mt. deer, short-faced bears, smilodons, the giant cave bear, the woodland muskox, the giant ground sloths, dire wolves, the Stag-moose, the giant armadillo, and on and on and on... The extinction list is way too long and diverse (including birds and reptiles) to simply tack it onto the butcher's bill of humans.

If by small numbers you mean 100s of thousands to millions of the people than yeah they could have easily drove those animals extinct.

About 3 million years ago, Panama arose out the sea and connected previously separated North & South America. This allowed the Saber tooth tiger to enter South America where they immediately reeked havoc and drove pretty all of South America's Ungulates, marsupials and large predators like Terror Birds extinct.

Now if small numbers of saber tooth tigers acting individually can drive a large number of animals extinct then it's not much of a stretch to see groups of humans who compared to Saber tooths are much more efficient and diverse hunters doing the same.

Especially considering one of early man's hunting strategies was to cause stampedes and drive whole herds of animals right off the sides of cliffs.

Extend the argument to it logical absurd conclusion. If man could wipe out mega-fauna as soon as they arrived, then why are there any animals in Africa where man was present many many years before in the Americas.

Extend your argument out to its logical conclusion and the Brown Tree snake couldn't be responsible for driving all those birds extinct on Guam because why are there any birds on the mainline where it was present for many, many years before it arrived on Guam.

And guess what, many large animals were in fact driven extinct by man in Africa earlier. There were larger species of giraffe, hippopotamuses, Hyenas, warthogs and several other large pachyderms living in Africa for millions of years, then Homo Erectus learned to sharpen sticks and build fires.

There were also large saber tooth cats living in Africa, they also went extinct at the rise of Homo Erectus. Why did they vanished in Africa while doing fine in the rest of the then people free world for 900,000+ more years, until man started his migration out?

Let me guess, these African extinctions were caused by asteroids also?

Sorry I know Asteroids and Comets falling out of the sky and killing all these beast sounds weally, weally cool and Asteroids/Comets means that ancient "at one with nature" man didn't drive all these animals extinct which keeps your Avatar fantasies intact, but sorry there is no evidence for them.

"If by small numbers you mean 100s of thousands to millions of the people than yeah they could have easily drove those animals extinct."

Except there is zero evidence that the human population density in N. America was anything like that high 12,000 years ago.

"This allowed the Saber tooth tiger to enter South America where they immediately reeked havoc and drove pretty all of South America's Ungulates, marsupials and large predators like Terror Birds extinct."

Well, that's one theory, anyway; but it's in direct contrast to another theory that holds that smilodon died out because they were too specialized in their prey and became extinct when that prey died out. They may have thrown off those feeding inhibitions once they went south...

"considering one of early man's hunting strategies was to cause stampedes and drive whole herds of animals right off the sides of cliffs."

They were still using that trick with buffalo when the Europeans arrived, and yet, the buffalo herds stretched from horizon to horizon and reportedly would take days to pass by, despite having been "over hunted" for thousands of years.

The theory is that the American animals had no fear of man. The animals in Africa and Eurasia evolved alongside humans and developed a natural fear of the predators.
