>>5689382https://en.wikipedia.org/wiki/Orion_correlation_theory#Leo_and_the_Sphinx>A date of 10,500 BC is chosen because they maintain this is the only time in the precession of the equinoxes when the astrological age was Leo and when that constellation rose directly east of the Sphinx at the vernal equinox.makes sense that the huge lion they build faces leo in the age of leo, and not taurus which is the age in which it was officially build and would have faced taurus at that time.
Furthermore there are indications of water erosions, hinting that the sphinx stood under water for some time even though the area is pretty dry for the last couple thousands years.
the 10.500 BC date also fits the alignment of the pyramids and angkor wat as well as the time göbekli tepe speaks of a comet crashing to earth which is now supported by mainstream science that a comet hit the earth causing an "Extraordinary Biomass-Burning Episode and Impact Winter"
>>5689396didnt knew about that instance, but doesnt suprise me since the pyramids already encode the speed of light due to their positioning themselves.
