Why don't they ask you to read and pray about the OTHER scriptures that they have??
Probably because their other two books, Pearl of Great Price and Doctrine and Covenants, are even worse. D&C is the book that dictates Mormon doctrine but directly contradicts the Book of Mormon at many points. PGP originally included photos of the papyri from which Smith “translated” the book. Then the Rosetta stone allowed linguists to decode hieroglyphics and it was discovered that the papyri were most inventory lists and whatnot. PGP no longer uses the illustrations.
