New evidence supports the idea that a huge space rock collided with our planet about 13,000 years ago and broke up in Earth's atmosphere, a new study suggests. This impact would have been powerful enough to melt the ground, and could have killed off many large mammals and humans. It may even have set off a period of unusual cold called the Younger Dryas that began at that time, researchers say. The idea that Earth experienced an asteroid or comet impact at the start of the Younger Dryas has been controversial, in part because there is no smoking-gun impact crater left behind as with other known events in our planet's past. But researchers say it's common for space rocks to disintegrate in the heat of a planet's atmosphere before they can reach the ground.
If a comet, which would have been traveling at about 30 miles per second, impacted Earth's atmosphere, it would have created a flash of extreme heat reaching about 3,000 to 4,000 degrees Fahrenheit (1,600 to 2,200 degrees Celsius). In addition to melting the ground, such temperatures would have proven cataclysmic to many kinds of life. At the same time that the impact may have taken place — 12,900 years ago — Earth was beginning a mini ice age. It is known that many large animals, such as the mammoth and the saber-toothed cat, did not survive this age. There's even evidence of a population decline in humans living in North America at the time, called the Clovis culture.

Did a great cataclysm happen around 12800 Years ago and then 11600 years ago ? That changed our early world ( Humankind )
This video published a few days ago on You Tube from the 2017 contact in the dessert UFO Conference
is well worth the long watch/Listen ?
