the lack of an impact site for the younger dryas plus the presence of widely scattered meteorite material—has suggested to scientists another scenario. that what caused the die off of the younger dryas was a gigantic comet airburst much larger than what occurred over tunguska siberia in 1908.

If you follow the space news with any kind of regularity you’ll notice how frequently there are near misses by all kinds of space objects. We really do live in a cosmic shooting gallery.
Another signature of a bolide impact is microdiamonds which also show up at younger dryas sites.
One of the guys on this thread posted a couple links on this above. Here is one.

Thanks - I’m knowledgable on the Tunguska event. And I keep up on the “near misses” (shouldn’t it be “near hits?”).
We have been lucky or, as is my wont to think, “blessed”.
Then there’s also the Yellowstone super-volcano that could decide to vent. We could get finished off from above or from below.
That’s if we aren’t crippled by a massive solar ejection beforehand!
