Since the bedrock of Mormonism is the Book of Mormon, which is proclaimed to be a "history of the ancient inhabitants of this continent," it should be expected that the millions of people described by that book should have left archaeological evidence of their existence.
No one can deny that great archaeological remnants are found throughout Central and South America. From the earliest days of the Church, Mormons have attempted to connect prehistoric architecture, pottery, and other archaeological remnants to the Book of Mormon. Dozens of books by Mormon authors have been published to this end.
The fact is that in recent decades, even Mormon scholars have had to admit that those kinds of connections cannot, with certainty, be made. In fact, many devout Mormons have concluded that no connection will ever be madethat, in fact, no such connection exists!
