The
Book of Mormon describes a vast pre-Columbian culture that supposedly existed for centuries in North and South America. It goes into amazingly specific detail describing the civilizations erected by the “Nephites” and “Lamanites,” who were Jews that fled Palestine in three installments, built massive cities in the New World, farmed the land, produced works of art, and fought large-scale wars which culminated in the utter destruction of the Nephites in A.D. 421. The Latter-Day Saints revere the
Book of Mormon as the divinely-inspired record of those people and of Christ’s appearance to them shortly after his crucifixion in Jerusalem.
The awkward part for the Mormon church is the total lack of historical and archaeological evidence to support the
Book of Mormon. For example, after the cataclysmic last battle fought between the Nephites and Lamanites, there was no one left to clean up the mess. Hundreds of thousands of men and beasts allegedly perished in that battle, and the ground was strewn with weapons and armor.
Keep in mind that A.D. 421 is just yesterday in archaeological terms. It should be easy to locate and retrieve copious evidence of such a battle, and there hasn’t been enough time for the weapons and armor to turn to dust. The Bible tells of similar battles that have been documented by archaeology, battles which took place long before A.D. 421.
The embarrassing truth—embarrassing for Mormons, that is—is that no scientist, Mormon or otherwise, has been able to find anything to substantiate that such a great battle took place.
