According to theosophic tradition the destruction of Atlantis occurred at 9564 BC. At about 9600 BC the Younger Dryas cold period ends. Pleistocene ends and Holocene begins. Paleolithic ends and Mesolithic begins. Large amounts of previously glaciated land become habitable again. Based on Plato’s Atlantis story, Atlantis is dated to about 9600 BC (9000+600). Solon died 558 BC, and 9000 years before that is 9558 BC.
Gobekli Tepe and Jericho both date to about 9600 BC. Below I show how 9554 BC was the first time (Zep Tepi). It defines the slope of Khufu’s pyramid, and the Kafre pyramid – Khufu pyramid azimuth(slope in regards to East). The first is accomplished when measuring the maximum altitude of star Vega at 9554 BC as seen from Gobekli Tepe. The second is done via measuring the maximum altitude of star Vega at 9554 BC as seen from Jericho. This was done by a very advanced civilization. They even left their signature – where they came from. Zep Tepi is not about Egypt and pastorial star gazers in Nabta Playa – in the hearts of the Sahara Desert. Its about planet Earth when they came.
With the above analysis and based on a 440 rc Khufu base length, the height comes out to be 280.122 rc. The measured best value for the height till now was about 280.23 rc , while the nominal is 280 rc.
