Well, that is not a problem when it comes to Facsimile No. 3 and the Explanations which have been canonized in LDS scripture.

And guess what? The Explanations of Facsimile No. 3 have been proven false through modern Egyptology. It's conclusive, Joseph Smith really couldn't read Egyptian. The early Mormons were duped.
