Ya know, all this evidential analysis is interesting and can definitely help your testimony at times, but if your REALLY trying to find out if the Bom is true, you need to not get caught up on the little details. You need to open your heart and really read and pray about the book of mormon. Even though everyone once in a while I hear controversial things about the Bom, theres always another side to the debate. Like the DNA thing for instance, i read this great article explaining and debunking that whole argument.. Anyways thats besides the point.
It's very heard to put aside all the things you hear from critics, but i have a testimony that if you do you will gain a witness of its divinity, and when you do hear the critics they will have no effect on you. Its really amazing. I went through the same thing, I always used to wonder and kinda doubt but after really wanted to know and reading and really paying attention in church and putting my heart and all my effort into it, I just know. Its weird cuz you think you would be swayed, but Its like i dont even budge. I just have that foundation. I cant explain it any other than that besides you just know its true and you are unaffected by any critical claims.
And also I as far as peoples claim that he just made it up... Lets see how you or anyone else would do trying to make a similar record!!!! This is an assignment at BYU:
"Since Joseph Smith was younger than most of you and not nearly as experienced or well-educated as any of you at the time he copyrighted the BOM, it should not be too much to ask you to hand in by the end of the semester (which will give you more time than he had) a paper of, say, five to six hundred pages in length. Call it a sacred book if you will, and give it the form of a history. Tell of a community of wandering Jews and involved them in all sorts of public and private vicissitudes, give them names—hundreds of them—pretending that they are real Hebrew and Egyptian names of circa 600 BC; be lavish with cultural and technical details—manners and customs, arts and industries, political and religious institutions, rites, and traditions, include long and complicated military and economic histories; have your narrative cover a thousand years without any large gaps; keep a number of interrelated local histories going at once; feel free to introduce religious controversy and philosophical discussion, but always in a plausible setting; observe the appropriate literary conventions and explain the derivation and transmission of your varied historical materials. Above all, do not ever contradict yourself! For now we come to the really hard part of this little assignment. You and I know that you are making this all up—we have our little joke—but just the same you are going to be required to have your paper published when you finish it, not as fiction or romance, but as a true history! After you have handed it in you may make no changes in it (in this class we always use the first edition of the BOM); what is more, you are to invite any and all scholars to read and criticize your work freely, explaining to them that it is a sacred book on par with the Bible. If they seem overly-skeptical, you might tell them that you translated the book from the original records by the aid of the Urim and Thummim—they will love that! Further to allay their misgivings, you might tell them that the original manuscript was on gold plates, and that you got the plates from an angel. Now go to work and good luck!
