You write "It's painfully obvious that G1/ Giza is a calender/ clock. "
It is also painfully obvious that most researchers do not double check their work. Take this latest video presentation. He has a line drawn from the north-east corner of The Great Pyramid through the center of G2 as defining a square BUT THIS ANGLE IS NOT 45 DEGREES SO THUS CANNOT AND WILL NEVER DEFINE A SQUARE AT GIZA.
And this is but one error.
