Historical authenticity of the Book of Mormon

The question of the historical authenticity of the Book of Mormon has long been a source of contention between most members of the Latter Day Saint movement and non-members. Most, but not all, Mormons hold the book's connection to ancient American history as an article of their faith. However, this view finds little acceptance outside of Mormonism. The theory that the Book of Mormon is an ancient American history is considered to fall outside academic credibility. Mormon apologists have proposed multiple theories tying Book of Mormon places to modern locations.

The Book of Mormon gives an account of two civilizations formed by families who migrated to the Americas. One group of families came from Jerusalem in 600 BC and afterward separated into two nations, known as the Nephites and the Lamanites. Another group came much earlier, when God confounded the tongues at the Tower of Babel; that group is known as the Jaredites. After thousands of years, all were destroyed except the Lamanites. Latter Day Saints claim that these Lamanites are among the ancestors of the Native Americans.

The dominant and widely accepted view among Latter Day Saints is that the Book of Mormon is a true and accurate account of these ancient American civilizations whose religious history it documents. Joseph Smith, whom most Latter Day Saints believe to have translated the work, stated, "I told the brethren that the Book of Mormon was the most correct of any book on earth, and the keystone of our religion, and a man would get nearer to God by abiding by its precepts, than by any other book." Unresolved issues of the book's historicity and the lack of supporting archaeological evidence have led some adherents to adopt the position that the Book of Mormon may have been the creation of Smith, but that it was nevertheless divinely inspired. Between these two views is the view held by some Latter Day Saints that the Book of Mormon is a divine work of a spiritual nature, written in ancient America, but that its purpose is to teach of Christ and not to be used as a guide for history, geology, archaeology, or anthropology.

Discussion regarding the historicity of the Book of Mormon often focuses on archaeological issues, some of which relate to the large size and the long time span of the civilizations mentioned in the book. A contemporary Mormon view is that these civilizations rose and fell in Mesoamerica. Civilizations of their magnitude and duration would be expected to leave extensive archaeological records. Several Mesoamerican civilizations did exist in the time period covered by the Book of Mormon, including the Olmec, Zapotec and Maya. The Olmec and Zapotec civilizations developed a writing system that may have served as the model for the later Mayan writing system, which became highly developed. The Maya developed a complex calendar and were advanced in astronomy and mathematics.
