That statement is mind jarring. Assuming a 90 degree axis tilt makes the difference between centered in the night sky and not even visible, a 23 degree tilt annually is a 25.6% impact in your "aligned to the galactic center".

Yet in your previous post you state this alignment happens every 174 years. Considering the pyramids are estimated to have been build 2,450 bce the median of 174 years would mean a 4% change would be diametrically off an alignment phase.

Thus in ONE argument you are willing to dismiss a 23% error (if we ignore, your words, not mine) but DEMAND an accuracy in construction phase of < 3%?

Rapidly moving? You are talking about greater than a 174 year cycle to a people who's average lifespan was 45 years or so. And what basis do you state "surely this is not the case for us"? Because your pet theory specially pleads for certain facts to be taken at face value?

Again, what did the AE use for "Starry Night"? To align planets they could NOT observe and were not aware existed?

AHHH you found the long awaited AE time capsule that gives the precise construction start date as 17-8-2466! Out of curiosity, was it Am or PM?

Show us the AE sculpted panel showing this alignment.
You seem to lose sight of the fact it doesn't amtter what YOU can do Ogygos, it matters what and why the AE did things.
