Researchers have discovered a possible connection between the fall of comet fragments to Earth 13 thousand years ago and
Their analysis confirms that the collisionhappened before the beginning of the Neolithic period in the southwest of Asia. During this time, people in a region that spans part of modern-day countries such as Egypt, Iraq, and Lebanon moved from a hunter-gatherer lifestyle to farming and establishing permanent settlements.
According to the team, a large number ofevidence supports the theory that a comet impact occurred about 13 thousand years ago. The researchers analyzed geological data from four continents, especially North America and Greenland, where the largest fragments are believed to have fallen.

Their analysis revealed an excess of the content levelplatinum, signs of materials melted at extremely high temperatures, and the detection of nanodiamonds that exist inside comets and are formed during high-energy explosions. All of this data strongly supports the impact theory, the researchers say.
The team says further research is needed to figure out how this might have affected the global climate and associated changes in human populations or animal extinctions.
