A controversial theory suggests that a group of comet fragments, believed to have struck Earth some 13,000 years ago, may have formed the origins of human civilization.
Experts believe that the cosmic influence that struck the Earth 13,000 years ago was so devastating that it turned humans from nomads into settlers.
The research suggests that the impact from this event, which likely caused the climate shift of the Younger Dryas, was likely the most devastating impact since the extinction of the dinosaurs and led to a mini-ice age that lasted for more than 1,000 years.
The study adds that before the start of the Neolithic period, which spanned from about 10,000 to 4,500 B.C., humans in the Fertile Crescent (an area comprising Egypt, Iraq and Lebanon) began to move away from the nomadic ways of hunting and gathering and shifting to life in permanent settlements. Reliant on agriculture perhaps in response to a changing environment.
Experts have speculated that influence from space may have significantly accelerated this stabilizing trend, although scientists are not sure why, and say more research is needed.
The study team wrote: “While it is possible with currently available scientific resources to ascertain whether a major cosmic impact event occurred at this time, it will likely remain difficult to separate the long-term consequences of such an event, and distinguish them from irrelevant causes. with influence.”
In the new study, the researchers, led by Martin Sweetman of the University of Edinburgh, looked at geological data for four continents, particularly North America and Greenland, from a previous study, and found “an excess of platinum, magma and nanodiamonds”, suggesting a significant cosmic influence.

Although rare on Earth, asteroids often contain high levels of platinum, and the researchers say this evidence strongly supports the cosmic influence theory.
And in 2017, an archaeological astronomical study suggested that humans noticed the impact and that the event was immortalized in stone pillars unearthed at the 10,000-year-old site of Göbekli Tepe in modern Turkey, possibly the “world’s first temple” that is linked to the origin of civilization in the Fertile Crescent in southern Turkey. west Asia.
In October 2019, scientists analyzed evidence at a South African site known as Wonderkrater, where they found high levels of platinum, which they believed supported the fact that a decaying meteorite hit Earth and caused a mini ice age.
Many scientists believe that this Ice Age wiped out dozens of species of mammals, including woolly mammoths, giant land animals, and decimated humans.
Another 28 spots around the world have platinum deposits similar to what was found in South Africa, indicating that a column of dust laden with platinum was sent into the air.
Experts say more research is needed to determine how much the cosmic effect actually had on the climate at the time, changes to humans and animal extinctions.
The new study was recently published in the journal Earth-Science Reviews.
Scientists first discovered the meteorite in 2015, and the meteorite strike in Greenland was not officially recognized until November 2018.
The Daily Mail previously reported that he left a 19-mile-wide crater that is believed to have caused the disappearance of the mysterious Clovis people in North America.
Described by NASA as “one of the 25 largest impact craters on Earth, it is nearly 1,000 feet deep and more than 19 miles in diameter.”
