The the book of Mormon reads like a clone of the King James Bible, if you are going to translate something you use the common language of your time period- and as TD pointed out, you don't include older Bible translation errors-
Every civilization leaves trash behind. Rubbish heaps tell us how ancient peoples lived- Those ancient lost tribes of Israel who according to Joseph Smith came to America in 600BC and established a great empire that lasted until 400AD- except, no artifacts and no trash has been found, no coins that the BOM says they used for money, and native Americans test negative for semitic dna. The Mormons have had about 10 years to deal with the dna results- for the most part, they have chosen to ignore the facts= their Book of Mormon is a work of fiction, not a heavenly revelation. What else do you call that, but a voluntary form of mind control-- and I never got to the Joseph Smith ancient Egyptian scam he pulled on everyone- he claimed to be able to translate hieroglyphics- before anyone else could. The Rosetta stone finally proved that Joseph Smith was a charlatan when it comes to his ancient Egyptian translation.--

It seems they knew all about metal working-- and maybe they even had a working iron foundry!!- They Mormons just haven't located these coins or that mythical iron works-
Ether 10:23, ( the Jaredites did) "work in all manner of ore, and they did make gold, and silver, and iron... and they did dig it out of the earth; wherefore they did cast up mighty heaps of earth to get ore of gold, and silver, and iron..
Iron could have saved the Aztecs from Cortez, except they used obsidian spears and clubs- iron working technology would not have been forgotten- it would have given any native Americans who had iron technology power over all of the Americas- stone, flint and copper can't stand up to iron.
