First, I apologize for any judgments about your responsiveness as AoM. Some GHMB posters expect a great deal despite the fact that they pay nothing for access to these boards. Gnostic/esoteric lore describes this as a "guest" mentality in life, which differs from the consciousness of a "host". The last AoM to take such gratuitous flak was Randall Carlson in December 2012.
Second, I am hopeful that you saw my considered response to your question in another thread. If not, please look at this in the "Free Book" thread you launched:
Third, I agree that the topic of Zep Tepi is far afield from what I understand The Christmas Code to be about. And I wish to commend your Magi/Herod take, which matches my own research findings. It's refreshing to find someone else who grasps widely misunderstood issues.
Fourth, again, you might find it interesting to know of the "0th Time" and "1st Time" views from the lost, ancient civilization. They differ greatly from our Westernized, English-based concepts, bringing an entirely fresh understanding of what "Zep Tepi" signified. I have yet to see a GHMB poster exude a grasp of the esoteric outlook.
And, fifth, esoteric Pythagorean traditions do identify the 1st Time (Zep Tepi) as nearly one millennium after the 0th time. (I am aware that the year of Zep Tepi is known among a few stewards of hidden lore, and you can safely bet that Graham Hancock and Robert Bauval pretty much nailed it.) In any event, Zep Tepi preceded the date attributed to Nabta Playa.
