I got mad respect for Graham Hancock's work, excellent writer and he does not try and put himself above the reader with his work. I am a late comer to his works,but I keep hearing positive feedback from the ether as I read, which when read honestly is very sobering because of the magnitude of the events that he unfolds in these verses.In the second of these two chapters here,try and put yourself on that bluff where he is holding a conversation with another gentleman who's great passion in life has been searching into these matters that they discuss,such as erratics and the Dry Falls(there is a geology lesson)...real good 'stuff'...

... Could certain ancient myths and traditions, judged to be of no historic value by scholars, in fact encode accurate recollections of an epoch when humanity experienced a crisis so devastating, so cataclysmic and so dislocating that we lost our memory of our true past? Consider this account from the Ojibwa, a Native American people:

The star with the long, wide tail is going to destroy the world some day when it comes low again. That’s the comet called Long-Tailed Heavenly Climbing Star. It came down here once, thousands of years ago. Just like the sun. It had radiation and burning heat in its tail.

The comet burned everything to the ground. There wasn’t a thing left. Indian people were here before that happened, living on the earth. But things were wrong; a lot of people had abandoned the spiritual path. The holy spirit warned them a long time before the comet came. Medicine men told everyone to prepare. Things were wrong with nature on the earth … Then that comet went through here. It had a long, wide tail and it burned up everything. It flew so low the tail scorched the earth … The comet made a different world. After that survival was hard work. The weather was colder than before …1

There are other interesting details in the various versions of this myth told among the Ojibwa and recorded by anthropologist Thor Conway. For example there is a reference to the comet killing off “giant animals … You can find their bones today in the earth. It is said that the comet came down and spread his tail for miles and miles.” 2 At the time of this event, usually referred to as “the first burning of the earth,” we’re told that the Ojibwa “lived near the edge of the Frozen Lands.” 3 It is also recorded that soon after the comet disaster “the first flooding of the earth” occurred. 4 https://exploringrealhistory.blogspot.com/2021/04/part-2-magicians-of-godsa-wall-of-green.html
