The Story of Adam and Eve (Unredacted)
This book was released in 1965. Afterwards, (I can't find the date) the CIA declared it classified and tried to round up all remaining copies. In 2016, they finally declassified the book per FOIA, but the version they have released has been heavily redacted. By my estimate the newly-released version is missing about half of the text.
After spending a few days trying to find an original copy of the book, I think this is it. It's a quick read; I have read it and it will blow your mind. It discusses the cataclysms from a geological, scientific, and historical perspective, including the great flood described by Noah and the one far earlier in the time of Adam and Eve. It retells parts of Genesis and other creation myths in the perspective of these geological observations and describes the cyclic nature of these pole-shift events. Amazingly, a 20+ degree pole shift (which is geological, not just magnetic) occurs in a matter of hours and can generate 1000+ mph winds and ocean waves 2 miles high or more.
Not sure if I believe what it says, but it is very much worth a read. I have no idea if this author is actually describing the truth, but it is suspicious that it was classified by the CIA when other books containing equally fantastic suppositions were not.
