Ralph Ellis is an airline pilot by profession with a passion for ancient history and religions. His revisionist views has been heavily criticised. He has authored a number of books(a) focusing, in the main, on ancient Egypt.
>The scale of Ellis’ revisionism, is, to say the least, breathtaking.
Jerusalem was not the capital of the ancient Jewish state!
King Solomon was in fact an Egyptian Pharaoh!
The Queen of Sheba was from Egypt!
Kind David and the pharaoh Psusennes II were the one person!
The Exodus of the Israelites describes the departure of the Hyksos! etc., etc.
Ellis concluded an old Atlantis Rising article(m) with the following,
“In essence, the whole of the Judaic—and therefore the later Christian – belief systems and iconography were based upon Egyptian antecedents. More importantly, perhaps, the historical characters whose lives spawned this religion, and the very book in which their entire history was written, were also Egyptian. The time has come to take a deep breath, to reassess all that we know of these religious beliefs, and to rewrite the entire theology of the world’s Judaeo-Christian cultures.”<
As noted elsewhere he has drawn attention to evidence for re-dating the pyramids. In an Atlantis Rising article in 2000, he argues that the ‘collapsed’ pyramid at Meidum was damaged by erosion that in his opinion would have taken more than the 5,000 years usually ascribed to it. He then turns to Khufu’s pyramid at Giza where he has identified evidence of erosion of pavement slabs that again seems to indicate a greater age than conventionally thought. Ellis proposed an age of 10,000 rather than 5,000 years. He has similar comments to offer on the state of ‘Bent’ Pyramid(j).
In a 2015 article(e) he claims that the four small shafts in the Great Pyramid had nothing to do with alignment with stars but were associated with the value of pi, an idea first suggested in 1859 by John Taylor (1781-1864)(i) in a book entitled The Great Pyramid: Why was it Built, and Who Built it? 
Ellis’ 2013 book, Eden in Egypt , locates the Garden of Eden in Egypt and claims that Adam and Eve were Akhenaton and Nefertiti!(n) He has also proposed(f) that Flavius Josephus was in fact, St. Paul! This latter idea has been taken up by others(g).
He has also co-authored a number of articles with Mark Foster(b).
In his trilogy, The Gospel of King Jesus, Ellis ‘reveals’ that Jesus was the great-grandson of Queen Cleopatra(o) and was King Izas of Edessa, in what is now northern Syria. Understandably, this has stirred up quite a controversy(a).
Ellis first touched on the subject of Atlantis in his book Thoth locating Plato’s island in the Atlantic, but in a later book, Tempest & Exodus he changed his opinion and subscribed to the Minoan Hypothesis.
Ellis has now turned his attention to ice age theory since the exact cause of the onset of an ice age is still a matter of active debate. He has now proposed a new theory based on a cyclical alteration of polar albedo by atmospheric dust(c).
In a recent paper published(d)(p) in Atlantis Rising magazine, Ellis reviews the mystery of the Carolina Bays, but offers little that is new and supports the growing consensus that the ‘Bays’ were the result of a cometary impact in the Great Lakes region, which was at that time covered by the Laurentide ice sheet. The impact shattered the ice and ejected millions of ‘slush balls’, many of which survived their high-speed journey through the atmosphere, creating the ‘Bays’ on landing.
>The World Mysteries website has a range of Ellis’ articles available(k).
For some sort of balance, you can read an extensive critical paper by Daniel O. McClennan, with some of Ellis’ responses to it(l).<
Another of Ellis’ weirder claims is that “there exists a large copy of the Great Pyramid way up in the Himalayas, highlighted in an article(h) and book, K2: Quest of the Gods” !
