In the last portion of the video I expressed skepticism that Hancock had independently "stumbled upon" the general idea that ancient Mississippian and Egyptian religions were related through their similarities regarding Orion, the Milky Way, etc. My skepticism came from the knowledge that there were, in fact, other sources out there at the time of Hancock's trip to Moundville wherein such comparisons were discussed. At the end of the video I invited Hancock to clarify where he got the idea.
I'm reproducing the three emails we exchanged below, in full (at his request). Hancock states that he had not read Greg Little's (2014) book Path of Souls at this time of his trip, and he points out that he did credit Little and Andrew Collins for their prior discussion of the idea. He also states that I am not telepathic and not inside his head. He is correct in both of those assertions, and it was wrong of me to speculate that he improperly took the idea from someone else.
