Why prehistoric people perish?

Scientists have found compelling evidence that a meteorite storm nearly 13,000 years ago seems to have destroyed the prehistoric humans and mammoths on Earth.

An international team of scientists, led by Dr. James Kennett of the University of California Santa Barbara (USA), has discovered a similar compound of molten glass - formed at temperatures between 1,700 and 2,200 degrees Celsius. - in a thin layer of rock in Pennsylvania and South Carolina of the US and in Syria.

'Extremely high temperatures are equivalent to a nuclear bomb explosion, which may be enough to melt sand into liquid glass , ' said Dr James Kennett, head of research, on the Daily Mail.

caused the prehistoric people and mammoths to perish.

In Syria, scientists found that glass-like material melted in lead coal in an ancient village in the Euphrates valley in Abu Hureyra region nearly 13,000 years ago. Dr James Kennett said the archaeological site in the Euphrates valley is also considered the birthplace of agriculture in the world.

The analytical results confirm, this material is not derived from volcanoes or humans created. Melted glass seems to resemble other substances discovered in Meteor Crater crater in Arizona, USA and meteorite fields in Australia.

From the evidence found on all three continents, scientists believe the molten glass-like compound is the result of a meteorite storm that occurred here about 12,900 years ago, causing the Earth to fall into one. an unusually cold period, leading to the demise of prehistoric people and many giant animals at that time.

In the cold period is called Younger Dryas , Clovis prehistoric civilization and a number of giant North American animals, including mammoths and giant land sloths that have permanently disappeared from Earth. . Clovis civilians were used to making bones and ivory as tools. They are also considered the first inhabitants of the Americas.
