07 - Oldest Time Marker
Original date of article: January 2019
Possible the oldest time marker of ancient Egypt that can be found may be the causeway towards the Pyramid of Chephren (Khafre) on the Giza Plateau.

So far, there hasn’t been given any explication for the fact this causeway makes an 14° south-east angle. Ok, the causeway towards the pyramid of Cheops also doesn’t lead exactly towards the east. The reason here is because there were already older mastabas in situ. However, that’s not the case at all for the causeway of Chefren. It would have been much easier if this causeway was going straight Eastwards, there was absolutely nothing in the way in this case.
The reason why may be that this way existed already from the earliest days in the history of Egypt and became much later a causeway for the pyramid of Chefren. The orientation is 14° south-east, however, this can also be seen as a 76° north-west orientation.
Given the fact that the author Robert Bauval  has shown that the three pyramids have a very special arrangement that can represent the galaxy Orion in approx. 10,500 BC it could well be that that causeway pointed in the direction where the geographic north pole was before the earth shift began or a little later, when they arrived in Giza. It is quite possible that the "newcomers" wanted to erect a monument here (three pyramids, causeway, etc.) to make clear to us what catastrophe occurred about 12,500 years ago.
If we accept this hypothesis, in this case the Earth's crust would have shifted by an angle of 76° instead of the earlier found 74.5 degrees. So, it’s now this new orientation that would have been oriented straight towards the former geographical North Pole (N1G).
The causeway towards the pyramid of Chephren isn’t the only construction with this 76° NW angle. Most parts of the valley temple are exactly north-south and east-west oriented and must have been built after the crustal shift had stopped. But, some corridors and/or chambers inside this temple have the same 76° NW angle and can therefore be even older than the valley temple itself. These remains, the causeway and a little part of the valley temple, may well be the remains of the oldest construction in Egypt.

The corridor in the valley temple of Chephren seem to have about the same 76° NW orientation.
Possibly the 76° NW orientation is correct and may indeed have been the start of the crustal shift. According to the author Robert Bauval  the three pyramids would represent the position of Orion at about 10,450 BC.
There may have been a much older causeway on the exact same spot then the one of Chefren's pyramid with the original direction of 76 ° NW. There is a possibility that the orientation of this causeway, along with the three pyramids, is the oldest time marker in ancient Egypt.
What then about the Avenue of the dead in Teotihuacan?
About 12,500 years ago, the avenue of the dead would have had an orientation exactly to the east. In addition, we assume that the exact orientation of the North Pole, around 12,500 years ago, now has a direction of 76 ° NW. However, the orientation of the avenue is not 76 ° but only 74.5 ° NW, which is a difference of 1.5 degrees. So, 12,500 years ago the orientation was not exactly East, but 1.5 degrees Southeast or, if you want, not exactly North but instead 1.5 degrees North East.
The avenue of the dead must have already existed some time before the earth’s crust began to shift. This avenue with his surrounding buildings must therefore already have been much older at that time. The only explanation for this difference of 1.5 degrees is the earths cycle of precession.
Earth's precession was historically called the precession of the equinoxes
See Wikipedia : Axial Precession
Calculating the angle of precession is very complicated and really a task for scientists.
Explained very simply, each terrestrial precession cycle would take around 26,000 years, with the inclination of the Earth's axis fluctuating between 21.5 and 24.5 degrees. For 13,000 years, the axis of the earth goes from the minimum 21.5 ° to the maximum of 24.5 ° in order to return the next 13,000 years from 24.5 ° to 21.5 °. In the case of the avenue of the dead, it is an angle of 1.5 degrees which, roughly estimated, could amount to 6,500 years, this avenue could therefore be 12,500 + 6,500 = 19,000 years old.
The Kalasasaya in Tiwanaku.
The ruins of Kalasasaya are located in Tihuanaca (Tiwanaku), Bolivia, about 10 kilometers south of Lake Titicaca. The Kalasasaya must have been an observatory and still today is almost exactly oriented towards the east. It was built after the crustal shift had come to a standstill again. But here too, the precession cycle caused a slight deviation. Arthur Posnansky has spent at least 25 years of his life studying this site. He came to the conclusion that this structure could be around 17,000 years old. Archaeologist Prof. Neil Steede has re-measured the site, this time with more sophisticated measuring devices. Because of that very small deviation from the exact east due to precession, he was able to establish that this observatory must be around 12,000 years old.
It is a bizarre world, Prof. Steede himself is an archaeologist and declared that the site is more than 12,000 years old. However, the majority of archaeologists claim that this site is less than 1000 years old.
