Yes, we believe the evidence of John Smiths existence just as we believe Jesus existed. Did you treat Mormonism with the usual sceptism-method for plagarism from other (biblical) beliefs?
Did you really just see the question,
"so you all agree then that Mormonism is true. "
and you thought a truthful and honest answer was,
"Yes, we believe the evidence of John Smiths existence "
You think that is an honest and truthful response to whether Mormonism is true?
