This may take 20 seconds or more to load, because it contains a lot of embedded videos. I’m doing a Youtube search on Third Millennium BC, since I’m interested in ancient cataclysms etc. The term is in the title or the caption. Easy way to post interesting stuff. This may be useful for my Substack at https://cataclysmicearthhistory.substack.com/archive.
Next one is just before 3rd millennium, but looks interesting.
