I missed this thread and had a read through the posts beneath it but will read them better later.

For the 39,000BCE c. time period, it is one whole Precession earlier than the 12,000BCE c. time period I like...Sirius at its lowest on the horizon. Having previously pondered such a thing, I wondered if it might have anything to do with the 5 relieving chambers above Khufu's pyramid's upper chamber, which then delves into great amounts of time that astronomy was appreciated and understood due to eons of watching what stars are not only doing, but how they influence cycles on Earth.

This kind of thing offers up what is meant when a tract of text describes the Sun rising and setting twice in the west...because of where the celestial field is in regards to the Sun, or vice versa.

Well, I'll read those posts and see where I am at in regards to them.
