"PROVIDENCE, R.I. [Brown University] - At the end of the Pleistocene
era, wooly mammoths roamed North America along with a cast of
fantastic creatures - giant sloths, saber-toothed cats, camels, lions,
tapirs and the incredible teratorn, a condor with a 16-foot wingspan.

About 12,900 years ago, these megafauna disappeared from the fossil
record, as did evidence of human remains. The cause of the mass
extinction and the human migration is a mystery. Now a team of
scientists, including Brown University planetary geologist Peter
Schultz, provides evidence that an asteroid impact likely caused the
sudden climate changes that killed off the mammoths and other majestic
beasts of prehistory.

In the Proceedings of the National Academy of Sciences, the
international team lays out its theory that the mass extinctions in
North America were caused by one or more extraterrestrial objects -
comets or meteorites - that exploded over the Earth or slammed into
it, triggering catastrophic climate change.

The scientists believe that evidence for these extraterrestrial
impacts is hidden in a dark layer of dirt sometimes called a black
mat. Found in more than 50 sites around North America, this puzzling
slice of geological history is a mere three centimeters deep and
filled with carbon, which lends the layer its dark color. This black
mat has been found in archaeological digs in Canada and California,
Arizona and South Carolina - even in a research site in Belgium.

The formation of this layer dates back 12,900 years and coincides with
the abrupt cooling of the Younger Dryas period, sometimes called the
"Big Freeze." This coincidence intrigued the researchers, led by
Richard Firestone of Lawrence Berkeley National Laboratory, who
thought that the black mat might be related to the mass extinctions.

So the researchers studied black mat sediment samples from 10
archaeological sites dating back to the Clovis people, the first human
inhabitants of the New World. Researchers conducted geochemical
analysis of the samples to determine their makeup and also ran carbon
dating tests to determine the age of the samples.

Directly beneath the black mat, researchers found high concentrations
of magnetic grains containing iridium, charcoal, soot, carbon
spherules, glass-like carbon containing nanodiamonds and fullerenes
packed with extraterrestrial helium - all of which are evidence for an
extraterrestrial impact and the raging wildfires that might have
followed.

Schultz, professor of geological sciences at Brown and an impact
specialist, said the most provocative evidence for an extraterrestrial
impact was the discovery of nanodiamonds, microscopic bits of diamond
formed only from the kind of intense pressure you'd get from a comet
or meteorite slamming into the Earth.

"We don't have a smoking gun for our theory, but we sure have a lot of
shell casings," Schultz said. "Taken together, the markers found in
the samples offer intriguing evidence that North America had a major
impact event about 12,900 years ago."

Schultz admits that there is little decisive evidence about the actual
details about the impact and its effects. Scientists suspect that a
carbon-rich asteroid or comets were the culprits. The objects would
have exploded over North America or slammed into it, or both,
shattering and melting ice sheets, sparking extreme wildfires, and
fueling hurricane-force winds - all of which could have contributed to
changes in climate that led to the cooling of the Younger Dryas
period.

"Our theory isn't a slam dunk," Schultz said. "We need to study a lot
more sediments to get a lot more evidence. But what is sobering about
this theory of ours is that this impact would be so recent. Not so
long ago, something may have fallen from the sky and profoundly
changed our climate and our culture."

If I hadn't found so much evidence of an advanced pre-history, I would
be wondering if some _thing didn't accompany that asteroid/comet (s)
and lead to an advancement of the human race to the degree that he
began to write and build cities.

One thing we don't usually pay much attention to, is the biological
change in nature, when you have severe sudden climate change. As a for
instance, in the North in Canada, if an area does not go below
freezing over a mild winter that normally would go below freezing, you
find an infestation of fleas, the following year, simply because they
would have died off over the winter.
Now its also possible to imagine a fungus, running rampant, as the one
which covered the entire earth, after the Great Dying.
Or even bacteria, if the climate was wet and mild. Or even a virus, or
any other small variety of life.
We don't usually think about the role the weather has on restricting
the growth of parasites.

Maybe the cold is better than to have a really mild global climate
because at least the parasites are inhibited by the freezing
temperatures.

What caused that mass extinction 12,900 years ago is anyone's guess I
suppose. Including alien attack from the moon.

What sort of attack?
Well you know Star Wars and the Death Star, well if you were to put a
charge on the moon's surface using some sort of huge power system, its
possible you could discharge a lightning bolt of Biblical proportions
onto the earth.
Maybe even " in more than 50 sites around North America"

Plato wrote something to that effect. That Zeus, um fired lightning
bolts at the earth, and that at times the planets wander from their
course, (or at least appear to) and so who knows and the earth is
destroyed by floods etc.

But this...
http://s2.supload.com/free/The_Moon-20070926024539.jpg/view/
hypothetically could be used as a capacitor. Although being able to
fire a bolt of lightning or electricity 85,000 miles, well that seems
like quite a bit of electricity.
What you would expect to happen is the site from where the bolt was on
the moon, that would basically turn to glass.
Like the mares as a for instance.
And where it hit the earth, well things would burn and there would be
the same sort of effect as a nuclear explosion without the radiation.
Enough to scare you into migrating.

Could this happen without alien control, without aliens or Zeus firing
the thing, could it build up a charge from cosmic rays and solar rays
and then discharge into the earth, by natural forces, well Velikovsky
said it could, but most people don't believe him.
