Hi Cold Steel,
"At the time the Book of Mormon came forth, no gold, brass or other metal records had been discovered."
There simply is no physical evidence the Book of Mormon is any older than when it appeared in the 1830s. Do you know of any? The existence of the KJV text in the Book of Mormon is not easily dismissed either. The production of the KJV in 1611 was a non-trivial exercise. I'm sure if the King James translators could see several consectutive chapters of their translation of Isaiah plagerized into Nephi they would rightly complain.
A further irony between the two faiths orbits around the divine name "Jehovah."
The KJV translators translated most Hebrew words into the equivalent 17th century English words. But in one special case, they decided to substitute rather than translate and that was... you guessed it... the divine name YHWH came out as LORD in English, rather than Jehovah. And since the divine name appears so many times in the OT, the KJV translators effectively signed nearly every page of their work. However, in one case in Isaiah faced with a double form of the divine name they translated Jah Jehovah as LORD Jehovah. See 2 Nephi 22:2 compared to Isaiah 12:2.
This of course is only the start of the problems. Surely one is left to wonder why a Greek word like "Christ" appears in a text that should have no Greek influence. The name Timothy also has this problem (3 Nephi 19:4).
When I was one of Jehovah's Witnesses I often would go online and discuss the LDS faith on Usenet a.r.m group. It was sort of like a safe proxy to explore my own faith. At the time I concluded we Witnesses had a more solid basis for our faith. At least the Bible is an authentically old collection of books with many aspects of verifiable historical settings. Since leaving the Witnesses and realizing how foolish some of my ideas were, such accepting Genesis creation and flood accounts as real history, my views on this have shifed. I would now argue that so much more is involved in a life-emcompassing faith like Jehovah's Witnesses and Latter-day Saints, that problems with faith claims wind up being easily dismissed at the first bit of apologetics we read, because the alternative would be world-shattering.
Cheers,
