The translation is a fraud, willingly committed by a man who knowingly deceived his followers. It has been documented as fraudulent by experts in and out of the church. This alone is enough to cast sufficient doubt on any of Joseph Smith’s claims.
The Book of Abraham was NOT a translation by Joseph Smith, but rather completely fabricated. The papyri he claimed to use have nothing to do with Abraham or anything else written about in that book. I remember that even as a teenager who knew little more about Egypt than what she had learned in elementary school, I knew that the items under the table in Facsimile 1 were clearly canopic jars, not idols.
This was what finally did any hopes of a testimony in. The gospel topic essays are clear in saying the papyrus is actually about a funeral, and not at all about Abraham. I can’t support that being true.
