I'm indifferent to the translation of the inscription - Khufu or Ra-Ptah or something else. It also is not critical whether or not it is a forgery. Of course it would be good to find out for sure, but I can't accept the opinion of either Zecharia Sitchin or Edgar Cayce as conclusive. And I don't have the background in hieroglyphs or pyramid construction to make any kind of judgment on my own.
Sorry I can't be more helpful on this one.
