One of the most persistent "faith-destroying rumors" (as I like to call them) about Book of Mormon archaeology is that we ought to have found much more "proof" (the real word is evidence) of the historicity of the Book of Mormon through archaeological discoveries by now.
Given that I am a big proponent of the well-established theory of Mesoamerica being the core of Book of Mormon civilizations and events, I'm sharing some insights from a recent article by National Geographic regarding the literally groundbreaking technology of LiDAR in the core of Classic Mayan civilization (ca. 250-900 AD), which is being used to revolutionize archaeological discoveries in our time. I'm going to do so in the context of the accusations made against Book of Mormon historicity claims.
CLAIM: "The scale of civilization as narrated in the Book of Mormon has never been discovered in Mesoamerica."
NEW EVIDENCE: “'Most people had been comfortable with population estimates of around 5 million,' said Estrada-Belli, who directs a multi-disciplinary archaeological project at Holmul, Guatemala. 'With this new data it’s no longer unreasonable to think that there were 10 to 15 million people there—including many living in low-lying, swampy areas that many of us had thought uninhabitable.'”
CLAIM: "No evidence has ever been found that Mayan civilizations as a candidate for Book of Mormon civilizations ever built transportation or urban infrastructure at the scale claimed by the Book of Mormon."
NEW EVIDENCE: "Virtually all the Mayan cities were connected by causeways wide enough to suggest that they were heavily trafficked and used for trade and other forms of regional interaction. These highways were elevated to allow easy passage even during rainy seasons. In a part of the world where there is usually too much or too little precipitation, the flow of water was meticulously planned and controlled via canals, dikes, and reservoirs."
CLAIM: "Nothing has ever been found in Mesoamerica to correlate with the idea that Book of Mormon civilizations had massive, decades-long wars involving defensive earthworks and large cities."
NEW EVIDENCE: "Among the most surprising findings was the ubiquity of defensive walls, ramparts, terraces, and fortresses. 'Warfare wasn’t only happening toward the end of the civilization,' said Garrison. 'It was large-scale and systematic, and it endured over many years.'"
To put all of this in even more perspective, this initial LiDAR survey covered a mere 800 square miles of the Maya Biosphere Reserve in the Petén region of Guatemala. Imagine what else we don't know and how much bigger the population and infrastructure scale could be with further LiDAR studies!
Further, what we see under the forest canopy is what remains of the 250-900 A.D. civilizations that build on top of prior structures. That puts what we know right at the end of the peak of Nephite/Lamanite interactions. The evidence we're looking for to cover the period of the first Nephite arrival (591-589 B.C.) and, further back, the Jaredite arrival (approximately the 3rd Millennium B.C.), is subject to discovery only after we've spent decades digging through the layers of the Classic and Post-Classic Maya remnants, if it can even be found at all after being looted/repurposed/decomposed.
I've said it before, and I'll say it again: those who claim archaeology will never uncover evidences of Book of Mormon historicity are simply not patient enough and/or don't have an understanding of how archaeology is a long-haul activity that often involves more uncertainty and questions the more discoveries are made. It is simply naive to think that one can sally forth into the jungles, dig a little bit, and find direct, clear, irrefutable proof of the existence of Jaredites, Nephites, and Lamanites. Too many confounding factors are possible through the complexities of time, the elements, and intermingling civilizations for that to be a possibility. Instead, we must take our time and carefully sift through data to find correlations that amount to a preponderance of evidence. We're far too early in our nascent understanding of Mesoamerican archaeology for that to have borne the kind of fruit that anti-Book of Mormon critics suppose should have been found by now.
The Book of Mormon is a volume of holy scripture comparable to the Bible and is a record of God's dealings with His chosen people in the New World. The main purpose of the Book of Mormon is "to the convincing of Jew and Gentile that JESUS is the CHRIST, the ETERNAL GOD, manifesting himself unto all nations." (Book of Mormon Title Page) It was written by ancient American prophets for our day (Mormon 8:35) and is an American testament of the Lord Jesus Christ.
