When we analyze what these M2C intellectuals are saying, we realize why so few people in the world take the Book of Mormon seriously.
M2C scholars have a list of justifications for their repudiation of the prophets.
For example, I've addressed a recent list of justifications here: http://bookofmormonwars.blogspot.com/2018/05/the-case-for-mesoamerica.html
Among the rationalizations are these "correspondences" between ancient Mayan civilization and the Book of Mormon:
2. Flags, banners, etc.
4. Cutting off arms.
5. "Requirements" from the text, such as these from BMAF/Book of Mormon Central America:
BMAF supports a Mesoamerican context for the major Book of Mormon sites. Other locations may meet some of the following criteria, but only Mesoamerica meets all these elements required by the book itself. This list of criteria is not a cafeteria list. Any Book of Mormon lands proposal must be able to demonstrate all.
A Narrow Neck of land and 4 seas (east, west, north, and south)
A major river running south to north from a narrow strip of wilderness
A high civilization with cities, kings, artisans, military, and priests
An agricultural base large enough to support several millions of people
A highly literate (written language) society with scribes as important officers
Functional calendar and dating systems
A merchant class using weights and measures
Engineers to build houses, temples, towers, and highways using cement
Highly skilled craftsmen working with precious metals and stonework
A warrior society involved in large battles using trained soldiers and sophisticated fortifications
Legends of a white, bearded God
Most people outside the M2C bubble easily recognize the circular reasoning here. The M2C intellectuals concoct a set of "criteria" based on Mesoamerica, not the text, and then transform these "criteria" into requirements. Let's look at each one, starting with the BMAF list.
The "narrow neck of land" is mentioned exactly once, in Ether 10:20. It's a description of the location of a great Jaredite city. But M2C conflates this passage with other passages that use different terms.
Nowhere does the text say "a major river" runs south to north. That said, there is a north-flowing river right in North America that M2C intellectuals don't know about.
A "high civilization" is ubiquitous in human history, including in North America.
The Book of Mormon never claims there were millions of Nephites. The largest enumerated army was only 42,000 (Mormon 2:9), and this was after the Nephites had been driven out of their lands and were collected together in one body. It was a time of blood and carnage, a time for "all hands on deck." Plus, we can look at the Bible for comparison. The Book of Mormon refers to a few places as "great cities." One is Jerusalem (1 Nephi 1:4; 2:13; 10:3; 11:13), which had a population of only around 25,000 when Lehi lived there. There is the "great city" Zarahemla. There is the great city of Ammonihah (Alma 16:9). There is Amulon's great city also called Jerusalem (Alma 21:2). And there are unnamed "great cities" round about (Helaman 7:22). These suggest a Nephite population of a couple of hundred thousand at most. Of course, the Nephite population could have been much larger, but there's nothing in the text that requires or even implies that. (Ether 15:2, which refers to two millions of mighty men who had already being slain, probably refers to the entire history of Coriantumr's people because Coriantumr was reflecting on what Ether had told him.)
The written language was expressly not Mayan, and from Enos through Moroni, the prophets explained that the Lamanites sought to destroy the Nephite records. That's why Mormon had to hide them in the depository in the hill Cumorah. Any society with abundant ancient written records cannot, by definition, be a Nephite society.
Calendars and dating systems are ubiquitous in human society. In North America, ancient people created earthworks that aligned with celestial events for this purpose.
Systems of weights and measures are ubiquitous among humans.
Cement is mentioned only briefly in Helaman 3 because the Nephites preferred to build with wood and earth. The text never mentions building with stone and cement, only with wood and cement. The only known Nephite cement is the material Moroni used to construct the stone box on the hill Cumorah in western New York.
Most human societies feature works of precious metal and stone, including those in North America.
Warfare and fortifications are ubiquitous among human societies, including in North America.
Legends of a white, bearded God... Seriously?
Now let's look at the other items.
1. Cities. The Book of Mormon refers to cities, villages and towns. What's the distinction among these terms?
When we assess Book of Mormon terminology, we look at the 1828 Webster's Dictionary and the usage in the King James Bible (references at the end of this post).
A "city" is a collection of buildings protected by a wall. (Towns and villages lacked walls.) In England, it was a community that had a bishop and a cathedral. This definition is interesting because there were seven churches in the land of Zarahemla, which the text says are "many churches" (Mosiah 25:22-23). Does that mean that "many cities" are actually "seven cities" or an equally small number? In Alma 51:26, a list of six cities is called "many cities."
We can't know for sure what the Nephites considered a city, or how many cities there were. But we do know that the indigenous people in North America built walls of wood and earth around their communities, which qualifies as cities, and there were many of these.
2. Flags, banners, etc. The Book of Mormon refers to the title of liberty, and Mayan culture also had flags or banners. But what human societies does not have flags or banners?
3. Volcanoes. M2C intellectuals insist that the destruction in 3 Nephi could only have been caused by volcanoes, but the text never mentions volcanoes. In reality, the destruction could only have been caused in Mesoamerica by volcanoes, but in North America, the destruction not only theoretically could have been caused by earthquakes; we have actual recorded accounts of such destruction taking place in the Mississippi river valley.
4. Cutting off arms. There are Mayan descriptions of cutting off arms. But this is a widespread practice in human societies. Trophy taking is ubiquitous among human societies. It's an ancient custom. Arm-taking specifically has been found in France (https://www.ancient-origins.
You can do the same analysis for any of the "correspondences" cited by M2C intellectuals.
This is not to show that the M2C intellectuals are "wrong."
The point is, these "correspondences" are illusory, and thus not an adequate justification for repudiating the prophets about the New York Cumorah.
