The terms sort of make this a difficult question. A historical error would be like saying the Germans invaded Poland in 1940. While there were (and are) Germans and Poles, and the invaision did take place it was in 1939. The book of Mormon recounts events about people, Semitic Jews in pre-Columbian America, that never existed. The lost city of Atlantis has as much arechological support as the events in the book of Mormon do.
