you need to read The Apocalypse of Yajnavalkya

and it is absolutely loaded with references related to recent discoveries, it was only published in early 2023 and it is VERY current

you will agree with the hypothesis once you read through about 1/4 of that book 

 I was thinking you were going to refer me to Graham Hancock. I've heard he has produced some books and shows related to Younger-Dryas and very ancient Earth history. 

 possibly it's a pseudonym but i think it's a lot more comprehensive than what i've heard about hancock

my sense is it's someone who studies all of these things intensely and is their first  book, someone very clever and careful
