Graham Hancock published the book titled "America Before",
with the subtitle: The Key to Earth's Lost Civilization.
I recommend the book and I hope I can be forgiven for revealing some details which really should be read in the book. My hard cover copy is 592 pages so to say there are many details is a severe understatement.
Joe Rogan interviewed Hancock many times, in his YouTube videos.
Some of these can be found by searching with the number after the #

Graham was on other non-numbered episodes.
I don't know how many are familiar with the Younger Dryas. This is an event of global warming that marked the end of the last global ice age.
People survived this cataclysm and apparently made monuments afterward, all over the world. This event spanned only a few years.
Graham is not an astrophysicist and proposes a massive solar CME hit the Earth causing this abrupt meltdown, and many sheltered in caves where they carved images.
This event was around 13,000 years ago, so it predates Velikovsky's work.
Velikovsky could not know of the ancient civilization in the Amazon, which is being revealed only in recent decades.
The works of Velikovsky covered civilizations spanning around the globe. He did not mention several in the American hemisphere dating back over 10,000 years ago.
I believe it takes awhile to grasp all the detailsin a book at almost 600 pages, but I found it very interesting. Perhaps some in EUT will also.
I posted this because I just saw (June 2020) Ben Davidson of SuspiciousObservers do an interview with Randall Carlson, in a YouTube titled:
The Sun & Earth Catastrophe | Randall Carlson/Ben Davidson
Randall has also done interviews with Joe Rogan and has worked with Graham.
Among those Joe Rogan episodes:
#501 in 2014
#961 in 2017
#606 in 2015
Graham has details on several important civilizations of varying capabilities but they share an incentive for solar solstice monuments.
This just a conjecture which requires research to put it together:
Perhaps these monuments to the Summer Solstice were a demonstration of celestial order in the universe.
a) some monuments were constructed after the Sun replaced Saturn which was the original most important light.
b) the monument confirmed the "new" Sun was consistent - and so it was stable, after the chaos.
Ben had Dr. Robitaille present at OTF2017, so maybe electric cosmology is converging with plasma cosmology.
