I don't believe that they were the same person... Why would Nefertiti not simply rule as herself? Tons of evidence shows that she had a lot of say in everything and control over Akhenaten. There is speculation that she was a foreigner named Tadukhepa (it is belived that she changed her name just before marriage to suit her new Egyptian-ness) that was originally sent to be married to Amenhotep III but when he died she was married to Akhenaten, and that she was the one that introduced monotheism to Akhenaten. I believe this. There's lots of evidence that Akhenaten loved her very much and I could see her converting him to her own religion.

I think Smenkhkare may have used the name 'Neferneferuaten' is honor of his mother... who was most likely dead by the time of his rule.

Like I'm writing in my book... I think that Akhenaten did not know of Smenkhkare and Tut's existence (hence no records of them as very young children) and so I think that Ay or Horemheb (or both) killed Nefertiti and erased most records of her existence and influence in Egypt. I believe that the mummy Dr. Joan Fletcher found is infact Nefertiti and Akhenaten buried her originally in a magnificent tomb and buried her as a pharaoh to honor her, I think tomb raiders nearly ruined her corpse and perhaps moved her body around.

That is quite a theory, Claude! I wonder, though.. Is what you are going on based on what you think happened, or is it actually based on probable evidence?

I'm really not an expert on this subject, so any new angle I can be presented with is welcome!

In any case, you've got an interesting theory that actually does make some sense!

I say we just ask Nefertiti what happened to her!
