Back to EpisodesThe Comet That May Have Nearly Wiped Out Humanity
Description
Around 12,800 years ago, Earth may have experienced a catastrophic event powerful enough to reshape climate, wipe out massive animals, and possibly reset early human civilization.
Some scientists believe the cause came from space.
In this episode of GL Deep Dives, we explore the controversial theory that a fragmented comet struck Earth at the end of the last Ice Age — triggering massive fires, sudden cooling, global disruption, and the disappearance of entire ecosystems.
Was this event responsible for the mysterious Younger Dryas period?
Could early advanced cultures have been lost in the aftermath?
And why does new evidence continue to reignite debate among researchers?
We examine:
- Geological evidence of extreme heat and impact debris
- Sudden climate collapse recorded in ice cores
- Extinction of megafauna across continents
- Ancient myths describing fire from the sky
- And the growing question: did humanity have to start over?
Sometimes history isn’t lost slowly… sometimes it’s erased overnight.
Welcome to GL Deep Dives.
