Some of Ralph Ellises work is mindblowing, the work of genius. Some if it is just favoured theories built around wild guesses. Mr Ellis may *like* the idea of Arkenaten and Nefertiti being Adam and Eve but there is no evidence for this, his evidence is called grasping at straws. It is ridiculous.
While I have no doubt Eden was in Egypt (the descriptions in the Book of Jubilees indicate this http://www.logoschristian.org/eden.html) or that Hebrew was based on Egyptian, or that the Jewish religion originated in Egypt, Arkenaten and Nefertiti bear as much resemblance to Adam and Eve as do Guinevere and Arthur.
Spend your money on one of Ralph Ellises other books - in Jesus he proves Abraham and the other Patriachs were Egyptian Pharoahs, in Solomon he proves King David was an Egyptian Pharoah, for this he should be acknowledged as the greatest historian of our time. Some of his other claims should be taken with a pinch of dead sea salt.
