You are basically comparing Book of Mormon to Quran?
More accurately I'm asking you why Muhammad is the real deal and why Joseph Smith is not. Unfortunately there is no way to prove this, which is why Joseph Smith is a really big help for my argument. You see.. there are only two options for you here:
a) Joseph Smith lied. This means Muhammad could have lied too.
b) Joseph Smith was telling the truth. This means the Quran might be wrong.
I suggest you go with option one. This will ultimately mean that you say you have been wrong in this entire discussion and it will mean that you can't prove Muhammad was either illiterate or alone when he "wrote" the Quran, but it will give you the opportunity to keep your faith.
