1. Geographic correlation
Hundreds of different geographic descriptions in the Book of Mormon — such as two seas, a narrow neck of land, a large north-flowing river and so forth — correlate with features in Mesoamerica.
2. High level of civilization
"There is civilization in Mesoamerica, and civilization is what the Book of Mormon describes," said John L. Sorenson, author of "An Ancient American Setting for the Book of Mormon." "Civilization, meaning cities — even great cities, large masses of people, large wars, big agricultural base for the economy, temples and towers and so on."
"In Mesoamerica, there are at least 15 types of script, of writing," Sorenson said. "The system of writing that is typical for Mesoamerica is all of the Egyptian style. … The only thing that is different about them is the characters."
