Scientists have discovered glass in the Atacama Desert (home to a large observatory!) was made by a cometary airburst:

https://www.ctvnews.ca/sci-tech/an-ancient-fireball-turned-kilometres-of-the-world-s-driest-desert-into-glass-1.5652482

about 12,000 years ago.

Could it be that the extinction of the megafauna, like iguanas that were as big as dinosaurs, was due to this, and not to the first people of the Americas? At first, despite the coincidence in time, that seems unlikely, as it wasn't enough to cause a mass extinction. Or was it?

The next thing you know, they'll have to rename Head-Smashed-In Buffalo Jump, a location in my current province of Alberta.

It has just been discovered that research causes cancer in rats.
