Well I don’t know if there really was a Jesus Christ. I just don’t see any direct historical evidence. I think if anything, he may have been a historical figure, who was a rebel with his teachings (was there eastern influence?) and started a movement, and then the god legends took hold after time. As I'm sure you're aware, the God story of has been repeated in different cultures, Mithra, Krishna, Osiris, etc. being born of a virgin, announced by a star and wise men coming to visit, crucifixion and resurrection in three days, 12 disciples, dying on a cross, Last Supper etc.

I debated between Peter or Paul, but I decided on Peter because there is some evidence of him, and he would've been a direct link. Paul on the other hand had a prominent role with the creation of Christianity.
For my fifth, I'm really leaning towards Joseph Smith. He is my heritage, and I think it would be totally incredible to be in his presence and feel the power of his personality. In fact, I did a search, and Time magazine has him listed in the top hundred Most Significant Figures in History at number 55.
