Interesting. There’s a hypothesis that Earth was struck by an impact 12,800 years ago in North America but the impact site wasn’t identified

https://en.m.wikipedia.org/wiki/Younger_Dryas_impact_hypothe...

Could these be related?

The evidence for multiple strikes around 12,800BP has been piling up for quite a few years now. There are other theories of course. A few papers :

If you actually click on the link, it mentions this both in the abstract, and a detailed comparison of evidence in a whole table.

I hadn't heard of this, but it says:

>The hypothesis is widely rejected by relevant experts.[2][1][3][4] It is influenced by creationism [...] It is an alternative to the long-standing and widely accepted explanation that the Younger Dryas was caused by a significant reduction in, or shutdown of the North Atlantic Conveyor due to a sudden influx of freshwater from Lake Agassiz and deglaciation in North America. [...] Authors have not yet responded to requests for clarification and have never made their raw data available

Is there a reason why the widely accepted explanation isn't satisfactory?

The publication of this research.

One possibility discussed in the publication is that the sudden influx of freshwater from Lake Agassiz was caused by the Perkins Louisiana impact.

It happened at the end of an ice age, when mile-thick glaciers were melting away. That’s a lot of fresh water going to the oceans.

[adastra22]

The argument is that the impact event(s) are WHY the ice age ended.

Ohhh… cool!

… and widely criticized as a creationist theory.
