I think someone else could make up a "gospel" just as Smith did.
1) The idea that Smith did it in only a short time is misleading. He may have been thinking about the story line for years. When he lost the first 127 (or however many) pages to a good fireplace's worth of kindling he went on and completely ignored those dozens and dozens of lost pages. If that was scripture, inspired nu God, it would not have been skipped over the second time around. If it was made up nonsense then it shows how prolific Smith could be. Wasn't Dickens just as prolific? I wrote a huge chunk of a doctoral dissertation in just a few months while working full time.
2) Maybe somebody should ask these questions:
a) Why are there horses in the BOM when none existed in the Americas before Columbas in the last few thousand years?
b) Why is there steel in the BOM when none existed in the Americas before Columbas?
c) Why is there silk...
d) Why are there chariots...
e) Why is there not a single shred of evidence to support the BOM?
