Ah contrare John, it documents that smith 'translated' significant portions of it WITHOUT the gift or instruction from 'god'. Your mythology also ignores the testimonies that smith stuffed his face in a hat too - why are you avoiding that John?
TImelines also show that smith had months and years to research (read plagerize ideas) his story in between writing events.
The written testimonies of the witnesses, printed in every Book of Mormon, ARE their testimonies, which none of them denied.
Written by smith and denied by their later actions.
David Whitmer testified that he did not see the plates literally with his fleshly eyes: He said he saw the plates "by the eye of faith" handled by an angel.(Palmyra Reflector, March 19, 1831)
David Whitmer changed his story about seeing the plates and later told of finding them lying in a field and later still, told Orson Pratt that they were on a table with all sorts of brass plates, gold plates, the Sword of Laban, the ‘Director' and the Urim and Thumim. (Millennial Star, vol. XL, pp. 771-772)
Why would Whitmer need to have faith first before he would see the plates - why were they shown as a result of 'supernatural power' if they were in fact physical plates. Why did they go into the wood and pray to 'see' the plates? Smith should have had them on hand according to the mythology you've been repeating. Why was prayer necessary at all if the plates were tangible. Whitmer also told about finding the plates in a field. Whitmer has so garbled his story, even the faith promoting myth of JS 3 just add to the compost that is the 'testimony' of the witnesses.
Glibly labeling as myth any experience that you don't agree with says more about you than it does about what you say is a myth. Joseph Smith III was an honest man. The experience he described was witnessed by several persons, none of whom have stated that Smith recollection of the experience is false. There is no reason for anyone to believe your statement that Joseph Smith's recollection is a myth, which implies that he lied about it. If you call anyone a liar that states anything that you don't like, what kind of person are you? Your attacks on other's beliefs without revealing your own suggests that you would not like anyone to attack your beliefs in the same manner in which you attack theirs. "Do unto others as you would have them do unto you" is a good teaching that I wish that you would learn.
