Authorship
I started reading the Book of Mormon in order to get a better grasp of its believability, but after only a few pages, I quickly grew tired of the writing. It seemed that the phrase "it came to pass" was in almost every verse. I decided to use my software copy of the Book of Mormon to count exactly how many times that phrase was used. The results and analysis are below.
| Book of Mormon | Verses | Came to Pass Used | Old Testament | Verses | Came to Pass Used | New Testament | Verses | Came to Pass Used |
| Jarom | 15 | 4 | Jonah | 48 | 1 | 1 Thessalonians | 89 | 1 |

total verses in 2 Nephi, 14 of the 33 chapters are copied directly
from Isaiah, so the verse count is based on only the remaining chapters.

I've sorted the books in each of the Book of Mormon, Old Testament, and New Testament in order of size by verse count. One can easily see from the chart the dramatic difference between Book of Mormon "authors" and the contemporary authors of the Bible. The extensive use of the phrase "it came to pass" in the Book of Mormon across all of the books, I believe, suggest a single author. The author, of course, in an attempt to make his work appear biblical in nature would use such words and phrases. It is not only that the phrase is used excessively, but also that the phrase is used inappropriately. Here are a few examples:
"And it came to pass that I, Nephi, returned from speaking with the Lord, to the tent of my father. And it came to pass that he spake unto me, saying: Behold I have dreamed a dream, in the which the Lord hath commanded me that thou and thy brethren shall return to Jerusalem." - 1 Nephi 3:1-2
"And it came to pass that I, Nephi, said unto my father: I will go and do the things which the Lord hath commanded, for I know that the Lord giveth no commandments unto the children of men, save he shall prepare a way for them that they may accomplish the thing which he commandeth them. And it came to pass that when my father had heard these words he was exceedingly glad, for he knew that I had been blessed of the Lord." - 1 Nephi 3:7-8
"And it came to pass that a long time passed away, and the Lord of the vineyard said unto his servant: Come, let us go down into the vineyard, that we may labor in the vineyard. And it came to pass that the Lord of the vineyard, and also the servant, went down into the vineyard to labor. And it came to pass that the servant said unto his master: Behold, look here; behold the tree. And it came to pass that the Lord of the vineyard looked and beheld the tree in the which the wild olive branches had been grafted" - Jacob 5:15-17
One can see in that in each of these quotes, that the phrase "it came to pass" is used not to denote that a great deal of time has passed, as one would expect, but only minutes or even seconds. In the third quote, especially, the author writes, "it came to pass that a long time passed away." Is anyone else thinking HEH?!? and scratching their head? This pattern of poor writing is consistent throughout the Book of Mormon, as the graph depicts.
I tested my budding theory on the word "exceedingly," which also occurs frequently in the Book of Mormon. The chart and table are below.

One can see the similarities between this chart and the "came to pass" chart. In both cases, the phrases are used exponentially more in the Book of Mormon. Of the books which had the phrase "it came to pass" used at least once, it is used in only 2.26% of the Old Testament verses, 1.65% of the New Testament verses, but in over 26.6% of the Book of Mormon verses. The word "exceedingly" is only used in 0.12% of the Old Testament verses, and only 0.14% of the New Testament verses, while it is used in over 5.06% of the Book of Mormon verses. Remember also, that the Book of Mormon, unlike the Bible, was supposedly written on golden plates. I wonder if Nephi ever got tired of etching "it came to pass" onto those golden plates . . . he only had to write it 200 times. Of course, he didn't have it half as bad as poor Alma, who wrote that fun phrase 415 times. I wonder if he just made some sort of stamp with "it came to pass" on it, so that he could just hammer the phrase or symbols in when necessary . . .
Finally, one other phrase caught my attention while reading the Book of Mormon. The phrase "in other words" struck me as a relatively contemporary phrase, not biblical in nature, but something that Joseph Smith may have used often. That phrase is used 12 times in the Book of Mormon across four different books (1 Nephi, Mosiah, Alma, and 3 Nephi). It is not used even once in the entire Bible, but it is used 23 times in Doctrine & Covenants and once in the Pearl of Great Price. Below are a few examples of its use, which further demonstrate that biblical prophets did not write the Book of Mormon.
"Behold, I have dreamed a dream; or, in other words, I have seen a vision." -1 Nephi 8:2
"even a Messiah, or, in other words, a Savior of the World." -1 Nephi 10:4
The first verse points out that a vision is the same as a dream. Is it really necessary to be that wordy, when you're etching your words into metal plates? The second verse points out the meaning of Messiah. Do you think that any Hebrew speaking person in that time did not know what a Messiah was? Do you think that any biblical author would find it necessary to explain that to his audience, especially when he had to etch it into metal plates? Common sense answers an emphatic NO to all of these questions.
I believe that all of this evidence points to a clear fact; that Joseph Smith was the single author of the Book of Mormon, that it was not translated, but created from his very creative imagination.
