Science in Jarom

1. The Nephites fortified their cities. (Why is there no evidence for these fortified cities?) 1:7

2. The Nephites "multplied exceedingly" and "became exceedingly rich" in gold, silver, iron, copper, brass, and steel making tools and weapons "of every kind." This was before steel existed, of course, and no evidence for any of these Nephite weapons, tools, cities, or technologies have ever been found. 1:8
