Experts believe that a cosmic impact that hit Earth 13,000 years ago may have been so devastating it changed humans from nomads to settlers.
The research notes that the impact from the event - which likely triggered the Younger Dryas climate shift - was potentially the most 'devastating impact since the extinction of the dinosaurs' and resulted in a mini Ice Age that lasted more than 1,000 years.
The study adds that prior to the start of the Neolithic period - which ran from about 10,000 to 4,500 BC - humans in the Fertile Crescent (a region comprised of Egypt, Iraq and Lebanon) were starting to move away from nomadic, hunter-gather ways of life into permanent settlements.
It speculated that the impact from space may have dramatically sped this settling trend up, although scientists are unsure why, and say further research is needed.
'Future research into [Younger Dryas]-related phenomena should, where possible, relate archaeological finds (such as megafaunal remains and stone tools) and other evidence (such as volcanic tephra) to their position relative to the Younger Dryas Boundary in the same time-series,' the study's authors wrote.
However, these claims are difficult to assess and establish, the study's authors added.
'While it should be possible with currently available scientific resources to ascertain whether a major cosmic impact event occurred at this time, it will likely remain difficult to tease apart the longer-term consequences of such an event, and distinguish them from non-impact related causes,' the authors wrote in the study.
'This major cosmic catastrophe seems to have been memorialized on the giant stone pillars of Göbekli Tepe, possibly the 'World's first temple', which is linked with the origin of civilization in the Fertile Crescent of southwest Asia,' the study's author, Martin Sweatman, from the University of Edinburgh said in a statement.
'Did civilization, therefore, begin with a bang?'
In the study, the researchers, led by Sweatman, looked at geological data of North America and Greenland from a previous study and found high 'excess platinum, quench-melted materials, and nanodiamonds,' according to the study's abstract, suggesting a major cosmic impact.
Although rare on Earth, asteroids often contain high levels of platinum.
In October 2019, scientists analyzed evidence in a South African site known a Wonderkrater, stumbling upon high levels of platinum, which they believed supported the fact that a disintegrating meteor hit Earth and caused a mini ice age.
The resulting ice age is believed by many scientists to have wiped out dozens of mammals species including the wooly mammoth and giant wildebeest and decimated the human population.
There are 28 other spots around the world that have platinum deposits similar to what was located in South Africa, suggesting that a plume of dust laden with platinum was sent into the air.
The experts say further research is needed to determine on how much of an impact the cosmic impact actually had on the climate at the time and what changes there were to human populations and animal extinctions.
The new study was recently published in Earth-Science Reviews.
First discovered in 2015, the meteorite strike was not officially acknowledged in Greenland until November 2018.
It left a 19-mile wide crater and is believed to have caused the disappearance of the mysterious Clovis people in North America, DailyMail.com previously reported.
NASA has described it as 'one of the 25 largest impact craters on Earth, measuring roughly 1,000 feet deep and more than 19 miles in diameter.'
In 2019, a separate group of researchers suggested that the event may have resulted in the extinction of more than 35 different types of large mammals, including woolly mammoths and mastodons due to 'extreme cooling.'
Another study published in March 2020 suggests that the impact event may have wiped out an ancient civilization in what is now Abu Hureyra, Syria.
