The people of Jared
The book of Ether
In the days of Limhi, twenty-four plates were discovered containing the record of an ancient civilization which started at the tower of Babel and ended in the complete destruction of a society that once remained for thousands of years.
These people knew that the Lord was angry with their rulers and pleaded with him not to confound their language. So because of their righteousness and through the lord's compassion they and their company were preserved. Thus began their long journey through the wilderness.
When they reached the borders of the sea, the lord commanded the people of Jared to build barges so that they could be lead to a promised land, which was choice above all other lands, which the lord had preserved for a rightous people.
Once in the barges, they were swept by a fierce wind for three hundred and fourty four days being tossed about in the waves of the sea until they finally reached land.
Antiquities of the Jews
There are in fact ancient accounts of the people being lead by God to their respective countries, even the building of ships.
Ancient Jewish historian Flavius Josephus, Gave added insight on the account of the tower of Babel concerning the dispersion of the people , "After this they were dispersed abroad, on account of their languages, and went out by colonies everywhere; and each colony took possession of that land which they lighted upon and unto which God lead them. So that the whole continent was filled with them, both inland and maritime countries. There were some also who passed over the sea in ships," Antiquities of the Jews Ch. V.
The choice land which the Jaredites came to was America. They were lead by the hand of God to this continent, and to the brother of Jared it was given a blessing and a curse that from this time henceforth and forever they should serve God or be swept off the earth. This is what was spoken to the brother of Jared the prophet.This promise still stands today for whoever will possess this land even the United States, Brazil, Mexico, Argentina, Peru, Canada, and all others abroad the Americas. Some may consider it hard to believe that this great country is impenetrable, but so was the case for the mighty nation of Jared, and we are forced to believe that the same state was in store for the people of Jerusalem who's fortified walls were penetrated by the Babylonians.
Jaredites and Olmecs
A Catholic priest named Ixtlilxochitl who wrote the history of Mexico in 1568 wrote that, after the great flood, the people built a very high tower. Their languages were confounded and they were scattered to all parts of the earth. They eventually came to Mesoamerica after having first crossed many lands and waters, living in caves and passing through great trials and tribulations. Most archaeologists and scholars date the Olmec culture between 2500 BC - 300 BC Though the Book of Ether does not give exact dates for the Jaredites, 2500 BC - 300 BC would be very close.
Both the Olmec culture and the Jaredite culture reached their zenith around the same time period (1500 BC - 600 BC). Ether chapter 10 tells us that the Jaredites built a great city with the whole face of the land covered with inhabitants. They worked in all manner of ore, fabrics, tools and weapons of war. The Olmec empire was heavily populated and covered a large part of the Gulf of Mexico area. While archaeological finds dating that far back are inconclusive as to the extent of metal use, etc.; the more discoveries that are made, the more advanced we find the Olmecs to have been.
