You are wrong!! The ball that led Lehi was made of steel!
[And it came to pass that as my father arose in the morning, and went forth to the tent door, to his great astonishment he beheld upon the ground a round ball of curious workmanship; and it was of fine steel. And within the ball were two spindles; and the one pointed the way whither we should go into the wilderness.. . .
[16 And we did follow the directions of the ball, which led us in the more fertile parts of the wilderness.]
It says so right here in my Revised Standard Book of Mormon the ball was made of steel, which is the only true rendition of the story of how the Nephites in 750 BC built a ship in the fjords of Scandinavia and crossed the ocean to land in Acapulco.
A steel ball with two spindles in it is no less out of time than Nephi’s steel bow:
[18 And it came to pass that as I, Nephi, went forth to slay food, behold, I did break my bow, which was made of fine steel; and after I did break my bow, behold, my brethren were angry with me because of the loss of my bow, for we did obtain no food.]
All the great bows through antiquity were compound and made of bone and wood, but Nephi had something no one in the whole region had, a pretty special people in 600BC.
