YDE Younger Drayas Event. All cultures have remnants of a VERY BAD DAY that may have had warning signs that have been passed down. Changes in the sky from the norm were universally assumed to portend disaster. Similar events may have continued at intervals throughout human history. But the YDE changed the whole world forever. Some religious notions now deemed backward were very practical back then.
Also read about some Greek and Finnish mythology that refers to fires from the sky causing a year of darkness and death. Parts of Kalevala in particular could describe very long held fears.
Would that be related to what I linked in #20?
