From what I understand (and I could be wrong), Mormons believe THEY are descended from that lost tribe of Israel.....is that right?
American Indian, they (lds) do beleive that these folks are descended from the lost tribes. There have been dozens of studies and genetic testing that demonstrates that AI, are in no way descended, yet mormons will tell you these were biased.
They (lds) sometimes refer to everyone else as gentiles, so conversely that would make them Jews or the “chosen”.
