I've offered to debate you and your "sources" before. Why haven't you taken me up on it? You said once that if I wasn't going to believe science, what was the point, but that's presuming the argument: I believe the current DNA evidence of Asian extractions supports the Book of Mormon, as I stated on my Mulekites thread. These statements reflect the scientists' knowledge of the Book of Mormon, not the Book of Mormon's knowledge of science. I agree with much of their data, I just know more about what the Book of Mormon actually says not to get caught up refuting the Readers' Digest version of it.
As for linguistic evidence, you've got to be kidding me! How did Joseph Smith know about chiasm (including megachiasm), Arabic couplets, Bedoin oaths and nomenclature, and colophons, just to name a few. What linguistic evidence do you have against the Book of Mormon?
