Were Prophets Reincarnated

Below are a few quotes that suggest that prophets lived as persons previous to their probation as a prophet.  Some people believe that prophets are men who were once exalted and who came to the earth to be a “great and noble” prophet.  Orson Pratt once claimed that Brigham Young taught that Jesus was exalted before coming to this earth.  Others believe the prophets were simply well developed individuals who had already experienced a goodly number of previous probations.  Some quotes seem pretty clear and other quotes seem less-than-convincing.  What do you think?  I invite your comments below: please share why you think these quotes should be interpreted to support either of these ideas or some other idea.
Please feel free to include your own quotes in your reasoning but please do not bother sharing any quotes post 1920 unless you think they are particularly persuasive from an academic (rather than religious) perspective.  Quotes post 1920 tend to do nothing more than decry these teachings as speculative and false and are therefore not helpful for this discussion.

Matt 16:13-15 | Mark 6:14-16
When Jesus came into the coasts of Caesarea Philippi, he asked his disciples, saying, Whom do men say that I the Son of man am? And they said, Some say that thou art John the Baptist: some, Elias; and others, Jeremias, or one of the prophets. He saith unto them, But whom say ye that I am? …

And king Herod heard of him; (for his name was spread abroad:) and he said, That John the Baptist was risen from the dead, and therefore mighty works do shew forth themselves in him. Others said, That it is Elias. And others said, That it is a prophet, or as one of the prophets. But when Herod heard thereof, he said, It is John, whom I beheaded: he is risen from the dead.

Wilford Woodruff | 1889

I have heard that in Zion there are some men who entertain the idea that they inherit the body and spirit of Moses, or Abraham, or David, or Noah, or somebody other than themselves. I hope none of you here indulge in anything of this kind, because it is a most foolish, nonsensical and false doctrine. You gaze upon a man who professes to have inherited the body or spirit of Moses, or any of those I have named, and I think you will conclude that his appearance does not indicate that such is the case; at any rate, it certainly has not improved him. Brother Woodruff, Brother Cannon, Brother Smith, Brother Lorenzo Snow, or any of the brethren, will never inherit anyone’s body or spirit but their own, in time or in eternity, unless the devil gets into them. It is Satan who inspires men to believe in such absurd things. He delights in having any of the brethren entertain false ideas, no matter what they are. I tell you that whoever sees me in time or eternity will see Wilford Woodruff, not Noah, nor Abraham, nor Enoch.  Every man has his own identity, and he never will lose that identity. Therefore, when you hear such doctrine as that advanced, do not believe it. There are a good many things Satan would like us to believe; but we must guard against these.
