"The Egyptians surely had no concept of North or other cardinal directions, they did not aim their pyramid exits to an abstract north but most surely to the center of the region of the imperisheable stars. That they get North was more ore less coincidence (because the center ot their suggested motion is in the North)."
The only problem with this is that they did not 'aim' the descending passages to the centre of the region of the imperishable stars.
The descending passages for the Dahshur pyramids were on average about 28 degs and the Giza pyramids about 26degs angle of incline. The 'centre' in the northern sky was about 30 degs altitude. Why the big difference?
The pyramids were laid out with incredible accuracy to the cardinal points so they were quite capable of 'aiming' the descending passages the the 'centre' if they had wanted to.
Any theory has to take into account all the subtle details, because this is where we are going to find the solutions - in the small details.
