I’ve read the Book of Mormon many times, and I love it so much. It’s a wonderful book, but when I think of a civilization that lasted 1,000 years in the Americas with hundreds of cities I wonder why there are no ruins or evidences of their fortifications. On the other hand, the Book of Mormon talks about metal swords, and in the Americas no type of metal has been found. Another thing, they said there were horses in the Americas, but everyone knows there were no horses until the Europeans came. Can you please help me with these concerns?
