12,800 years bp – Big Impact

A cosmic impact about 12,800 years ago caused the Younger Dryas – a glacial surge which reburied the world in ice for a thousand years. So not an Ice Age, but a chill-down. The same events probably caused the extinction of a multitude of species and obliterated any human culture unable to adapt to the cold.

No one knows what it was for, but a good guess is that it was an astronomical structure, designed to map the sky at the time. If small impactors are raining down from the sky regularly, it has a clear purpose.
