Canadian geologists have found more evidence that impact craters may, in fact, be the best places to look for signs of past life on Mars and other worlds, and could even have been the place life began on Earth... It was during some field work on the 15-mile (24 kilometer) wide Haughton crater that he and his colleagues recognized what appeared to be the remains of hydrothermal structures. These would have been steaming vents at one time, releasing heat for millennia that had been generated by the impact event.

Northern Crater Shows Prehistoric Deep ImpactTo the rhinos and crocodiles of the far north, the day was like any other. They ate, swam and napped, unaware a celestial body was headed their way at 60,000 miles per hour. Suddenly, a wayward comet screamed into the atmosphere, struck Earth and created a bowl a mile deep and 15 miles in diameter.
by Ned RozellMars On Earth: Arctic Crater Reveals Martian Secrets (pt 2)Haughton Crater is the remaining scar from a high-speed collision between Earth and some heavy object from space about 23 million years ago. The comet or asteroid that created the crater was perhaps more than a mile (up to 2 kilometers) across and slammed into the forest that existed on Devon Island. Everything was annihilated for scores of miles in all directions. The impact churned up rock from more than a mile below the surface, vaporizing much of it. It's estimated that between 70 and 100 billion tons of rock was excavated from the crater in the moments just after the impact. While clouds of dust and gas filled the air, rock rained down from the sky, much of it in the form of what geologists now call breccia, which simply means "broken up." Scattered within the breccia are pieces of a rock called gneiss that normally is dark and dense. In Haughton Crater breccia, the "shocked gneiss" resembles pumice stone -- it's ash-white, porous and very lightweight.Voices of the Rocks"Yet, as it will, life returned to this site of complete devastation... The world those fossils described, the one that flourished on the order of 20 million years ago, during the early Miocene epoch, was strikingly different from today's Arctic... Devon Island was covered with a forest of birch trees and conifers, a landscape that one now finds about 2,000 miles to the south, in Minnesota, Wisconsin, and Maine.

"Even farther back, on the order of 45 to 65 million years ago, during the Paleocene and Eocene epochs, the fossil record shows Devon Island to have been still more profoundly different. Back then, what is now the Arctic was a region of swampy lowlands, slow-moving rivers, and towering forests of dawn redwood, kadsura, and ancestral forms of hickory, elm, birch, sycamore, and maple. Primitive fishes, crocodiles, salamanders, newts, and turtles inhabited the rivers and marshes, while the forests and meadows supported flying lemurs, early primates, forerunners of today's cats and dogs, and ancestors of the rhinos, tapirs, and horses."

Could this mean that Sitchin was right?
Yes! This is how my friend shaggy eel got here. He said it gave him quite a headache for a while, but he eventually forgot about it with all the food around.
Kind'a have a hankerin' for some tasty primitive fishes, crocodiles, salamanders, newts, turtles, flying lemurs, early primates, and ancestors of rhinos, tapirs, and horses right about now, myself.
Uh, no.
In his very first book, "The Twelfth Planet", Sitchin claims that a planet Nibiru is in a 3600 year orbit around the Earth. One contemporary reviewer pointed out that Sitchin apparently sync'ed this such that the most recent pass of the planet was in the late centuries B.C., an event for which there is no testimony. The reviewer also pointed out that the supposed information from the aliens regarding the extent of the orbit was incompatible with Kepler's laws.
mmmm, tasty.

Global warming - good for biodiversity! ;)
Hey....leave some for the rest of us !!!
(shaggy found some more Orcs you may be interested in.....)
;') Of course, the problem with the scenario (including these thermal vents) isn't the heat, but the food supply. Unless there is sufficient sunlight, the basis for the food chain -- plants -- won't grow. Mice and rabbits don't eat fish. (':
Crunchy...with a hint of spice....
I was just kidding. Actually, I have a lot of fun with Sitchin's books. A real enigma. He's nothing less than an expert on the early civilizations of Sumeria, Babylon, etc; especially adept at reading the scrolls and understanding the language of those civilizations and then totally blows all credibility with his 12th planet nonsense. I suppose it's because playing to the Von Danikin crowd sells a heck of a lot more books than playing straight. If you care to read just one of his books that has a lot of interesting intellectual insights on the origins of civilization similar to the stuff you post here, I'd recommend "When Time Began" but fair warning, you still have to gloss over the 12th planet spacemen stuff to get to the good parts.
"I suppose it's because playing to the Von Danikin crowd sells a heck of a lot more books than playing straight."
Definitely. And predicting a planet will take a spin through the inner solar system, reaching perihelion more than 1000 years from now, after Sitchin and the rest of us are dead and forgotten, looks like genius marketing. :')
