Conference on Precession and Ancient Knowledge, otherwise known as CPAK, has taken place annually over the years and has been very informative and interesting to many attendees in the Sedona, Arizona area.
Top authors and scientists, including Graham Hancock and John Major Jenkins, have discussed the topic of precession, both from a modern and ancient perspective, presented arguments supporting a cyclical theory of civilization, and highlighted potential archaeological, mythological, or astronomical evidence surrounding these theories.
