Where did the events in the Book of Mormon occur?  North America? Mesoamerica? What does the evidence say? Although the LDS Church has taken no official position on where Book of Mormon events happened, it is important to carefully read Book of Mormon passages which help narrow the possible locations. The Book of Mormon describes Jesus healing those with leprosy. Leprosy was found only in Mesoamerica before Columbus, not in North America. The BoM describes cement cities, found only in Mesoamerica, not in North America. In the final battle between the Nephites and Lamanites, 240,000 died. During BoM times the largest population center in all of North America, the Cahokia, in present day Illinois, had less than 10,000 inhabitants. 2018 LiDAR scans conducted by the National Geographic Society, demonstrated that between 15 and 20 million people lived on the Yucatan Peninsula during BoM times, easily large enough to support a final battle in the BoM in which 240,000 died. These and many other evidences strongly suggest BoM events happened in Mesoamerica, not North America.
