What is Biblical Prophecy Really? Could Moses have been hanging with aliens or hallucinating? What does Carl Sagan have to do with it?

In this extended class, I discuss the origins of Biblical prophesy, historically and contextually, and we ask ourselves about the very nature of Revelation.  Was it dictation from the sky?  Was it ancient aliens?  Was it hallucination?  Why were light beams shooting out of Moses' head?  And I also mention the relevance of the Carl Sagan book (and best movie about religion of all time) "Contact."  To quote Matthew Mcconaughey in that movie, "Hey hey hey... it was God!"
