Skeptics and most archeologists believe that the Book of Mormon is a hoax, and that it was written in the early 19th century by Joseph Smith or some other individual(s). There are no proofs, but there are some really strong indicators.
Who Wrote the Book of Mormon?
Actually, you are not far off. The BoM was a plagarized and added-to version of Solomon Spaudling’s “Manuscript Found”. The religous content was added by one Sidnney Rigdon as he had been recently cast out of the Campbellites.....a great deal of the doctrine of the Mor_ons is Campbellite belief that Rigdon was unable to pary into wealth for himself. The whole thing is an absolute hoax...a con game to make money, but there are still those today that buy it hook, line, and sinker....very sad.
I guess they have nothing else to stand on.
