Anything is possible, Merytre-Hatshepsut. Nobody knows anything about Tutankhamen really. Psusennes could be coming up with his own theories just as everyone else has. Just because it's not what most people believe, doesn't make it nonsense.
People can come up with theories, but they should be based in fact.
There are no court records, his translation of Tut's name is wrong, there is no twin brother, and like I said there are problems with almost all of his comments.
Your comment about "Nobody knows anything about Tutankhamen really." is just not true. There are quite a few problems with our knowledge, but we do have a certain amount of information.
I totally disagree that we have to consider any theory people come up with. There is a certain amount of information from the archeological record that your theory should incorporate.
I think he was giving this misinformation on purpose. Which I think is a really bad attitude.
I actually can't believe that the moderators are letting something like this go on.
Feeding disinformation to a student is just disrespectful and I find the attitude rather nasty. As a professor at a university, I find the idea of reacting to a student's questions in this way (which I think amounts to ridicule) just unaccceptable.
Not to mention that this king of nonsense undermines the credibility of your website.
And yes, no doubt what he wrote is just factually wrong. Enough is known to determine that.
And that's all I will say about this....
