Gary Gilligan (1957- ) is a British author who has “studied Egyptology, Astronomy and Geology with an almost obsessive passion. When he first came across the theory of catastrophism, he was intrigued by the possibility that the Solar System had undergone recent upheavals due to cosmic chaos.”
Gilligan is arguably the most radical of the catastrophists and ancient chronology revisionists publishing today. Some of his ideas make those of Velikovsky as well as James and Rohl seem somewhat tame.
Among his many extreme claims are (1) Our Moon was only captured in the first millennium BC(a), (2) The Saharan sands, he claims are extraterrestrial in origin , (3) The ancient year had only 360 days(b) and (4) The ancient Egyptian climate was milder than today as indicated by a red sun, rather than today’s yellow disk!(c)
>In a short 2012 paper now republished in October 2022 on the Thunderbolts website Gilligan proposes that the Amazon rainforest is only a few thousand years old. He argues that the Amazon region is today dependent on the 54,000 tons of fine dust received daily from the Sahara and since the Sahara did not exist 6,000 years ago neither did the Amazon rainforest which he says is claimed to be 55 million years old!(d) However, an article from Scientific American (July 7, 2014) also offers an even more recent date for the development of the rainforest, suggesting that “the people of the Amazon from2,500 to 500 years ago were farmers.”(e)<
