*Scientists find 'melt-glass' in 12,000-year-old rock
*Melt glass forms at 1,700 degrees - equal to atomic bomb
* Meteorites thought to have triggered a cold snap that killed off early civilisation and giant animals
Scientists have found compelling evidence that a meteorite storm hit the earth more than 12,000 years ago, and is likely to have been responsible for the extinction of a prehistoric people and giant animals including mammoths.
Evidence of the meteorite’s intense heat was found on two continents. The researchers believe the huge cosmic impact triggered a vicious cold snap, which caused widespread destruction.
The international team found a substance known as melt glass, which forms at temperatures of 1,7000 to 2,200 degrees Celcius and can result from a ‘cosmic body’ hitting the earth.
New scientific findings suggest that a large comet may have exploded over North America 12,900 years ago, explaining riddles that scientists have wrestled with for decades, including an abrupt cooling of much of the planet and the extinction of large mammals.
According to the scientists, the comet before fragmentation must have been about four kilometers across, and either exploded in the atmosphere or had fragments hit the Laurentide ice sheet in the northeastern North America. Wildfires across the continent would have resulted from the fiery impact, killing off vegetation that was the food supply of many of larger mammals like the woolly mammoths, causing them to go extinct. Since the Clovis people of North America hunted the mammoths as a major source of their food, they too would have been affected by the impact. Their culture eventually died out.

Well science has determined that the story of Sodom and Gomorrah was most likely a meteor exploding in the upper atmosphere (or even struck), so it's wholly (holy, lol) possible.edit on 16/6/12 by woogleuk because: (no reason given)

I saw a documentary that was about this. They found tiny meteorite fragments in the tusks of mammoths.
That, they said, was evidence of a large strike that killed off the larger animals. The reason they couldn't find a crater was due to the angle of entry and the ice sheet covering the region at the time.
Bullet-like pieces of what is thought to be an ancient meteorite shower have been found embedded in mammoth tusks and bison bone. The discovery of the 2–5 millimetre holes left by meteorites opens a window into a impact event thought to have happened over Alaska and Russia tens of thousands of years ago. And it could provide a whole new way to chart impacts from space.

Ever think of the possibilities of a super nova flash...that would decimate everything above ground at least....There were ancient bones found in India that were laced with radiation and also melted rock that met similarities to nuclear explosions...hmmm...major solar engulfment......dam,look at the moon.Has any of those craters been dated?(samples please)
"A gamma-ray burst originating within 6,000 light years from Earth would have a devastating effect on life," said Dr. Adrian Melott of the Department of Physics and Astronomy at the University of Kansas. "We don't know exactly when one came, but we're rather sure it did come -- and left its mark. What's most surprising is that just a 10-second burst can cause years of devastating ozone damage."

No, really, where did you get this stuff? Im not seeing a link in the OP. Otherwise, this is already a great thread. Especially with the input from Kdog.

Perfect example of how to debunk Ancient Astronaut theory. They say nukes and advanced ancient alien civilization, science says rocks hit planet.
Whom do you believe?
