Joseph Smith was not a prophet

A.  Multiple conflicting versions of the First Vision, in which aspects of the story as fundamental as the number of personages who appeared to Joseph Smith during the First Vision varies from one angel, to Jesus Christ alone, to God the Father and Jesus Christ as two personages, to one version in which hundreds of angels appeared to Joseph

B. Could God not find someone to restore his church who wouldn't marry other men’s wives behind their back while keeping it a secret from his wife and the church's members for years?

C. Joseph Smith brought about the Book of Mormon by putting his face in a hat and staring at a seer stone while the church depicts him bringing about the book of Mormon by translating the golden plates. Joseph often wasn't in the same room as the plates during translating.

D. Joseph claimed he was better than Jesus-  Address of the Prophet - His Testimony Against the Dissenters at Nauvoo. “In all these affidavits, indictments, it is all of the devil--all corruption. Come on! ye prosecutors! ye false swearers! All hell, boil over! Ye burning mountains, roll down your lava! for I will come out on the top at last. I have more to boast of than ever any man had. I am the only man that has ever been able to keep a whole church together since the days of Adam. A large majority of the whole have stood by me. Neither Paul, John, Peter, nor Jesus ever did it. I boast that no man ever did such a work as I. The followers of Jesus ran away from Him; but the Latter-day Saints never ran away from me yet.”

I'll have to add more later. Bottom line- the best word for Joseph isn't prophet but rather profit- as in he was in it to profit his own ego, pocketbook and sexual desires.
