As to the question of historical and archaeological authenticity: Can you prove to me that Jesus Christ was resurrected from the Dead and ascended into Heaven after teaching his disciples for forty days?
In both cases, that of the resurrected Lord and the Book of Mormon, witnesses beheld Jesus and the plates from which the Book of Mormon were written. Both groups bore witness that an angel confirmed the truth of what they saw. Witnesses touched the wounds in the Saviors hands and feet. Witnesses handled the Gold Plates and touched the engravings on the pages. I submit to you the the evidence for the Book of Mormon is as strong as the witness for the Resurrection of Jesus.
