Quote #1 is from an essay by Mike Ash:

Quote #2 is from this article:

#2 is a book review where the "evidence" about the BoM amounts to speculation derived from unverifiable claims. For example, the second article has the text:
Notice the bolded parts. The "evidence" offered for horses in the Americas during the BoM's time frame consists of "bone fragments" an author CLAIMS to have collected and CLAIMS to have sent out for testing. The actual research is unpublished, and no data is given as to which Carbon-14 dating method was used or who did the testing. More to the point, this claim about mystery bone fragments is coming from a BOOK REVIEW, not even the person claiming to have collected the samples and sent them out for testing.
I encourage everyone to read both articles in their entirety. Both are an excellent study in cognitive dissonance.
The book review is of "
Science and the Book of Mormon: Cureloms, Cumoms, Horses & More" by Wade E. Miller which isn't published in a scientific journal of any kind. The author is a Brigham young professor whose writing credits are limited to similar apologetic work, and one contribution to
a book about the 2012 presidential election (ZOUNDS! Check out what they're asking for the Kindle edition!). I haven't found any evidence of him having published in any scientific journals, but that doesn't mean he's COMPLETELY devoid of credibility, I just haven't found anything beyond his BYU degree.
