Two "diasporas", one at the tower of Babel, the others, the scattering of the Twelve Tribes, being lead by the hand of the Lord to the "nethermost part of the vinyard", twigs broken off and planted by the Lord through the means of his servants the prophets.  One such came out of the Tower of Babel, whose language was NOT confounded.  They wrote in the Adamic language, one portion of which was included in the sealed portion of the gold plates, the small portion of which Joseph Smith translated by means of the Urim and Thummim. Tablet stones found in Michigan by multitudes of people at the turn of the century, while plowing fields, digging basements, along with mine shafts, 10,000 mounds in Ohio alone.  A video of one collection (Soper Savage) of these can be seen here. There are at least 30 other collections.
