This first part is based in RET.

Precessional movement of the Earth. The Earth rotates (white arrows) once a day about its axis of rotation (red). This axis itself rotates slowly (white circle), completing a rotation in approximately 26,000 years.
This causes the pole stars to change slowly over time, as the "plane" of the sky changes relative to the Earth.

The famous star Polaris is a pole star that is about one degree from the North Pole. However, at about 3000 BC, Thuban was the north pole star.
This has been observed. The Pharoah Khufu in ancient Egypt built the largest of the Pyramids of Giza, known as the Pyramid of Giza. He based the construction of it on Thuban, then known as "Alpha Draconis," the brightest star in the constellation Draco, the serpent. Khufu expected that when he died, he would join not only with the Sun, but with Thuban as well, maintaining order in the celestial realm, just as he had on Earth.

According to FET this won't happen, because there is no axis at all. If we were to imagine a line through the North Pole, perpendicular to the flat Earth, it would never move. The celestial sphere would never move either and the pole star would never change. However, it does and it affected the Pharoah.
