There is even a tradition in the Bhagvata Purana that the greatest sages ‘range over the world in the guise of mad persons’ whilst imparting wisdom. - Graham Hancock

a team of Japanese engineers had recently tried to build a 35-feet-high replica of the Great Pyramid (rather smaller than the original, which was 481 feet 5 inches in height). The team started off by limiting itself strictly to techniques proved by archaeology to have been in use during the Fourth Dynasty. However, construction of the replica under these limitations turned out to be impossible and, in due course, modern earth-moving, quarrying and lifting machines were brought to the site. Still no worthwhile progress was made. Ultimately, with some embarrassment, the project had to be abandoned.

If the Edfu Texts contain a record of these events, as I have proposed, then we should take seriously the message they transmit, that there were survivors of the cataclysm who made it their mission to bring about: 'The resurrection of the former world of the gods. ... The re-creation of a destroyed world.'
These survivors are said to have wandered the earth, setting out and building sacred mounds wherever they went, and teaching the fundamentals of civilization, including religion, agriculture, and architecture.

We are used to things starting out small and simple and then progressing — evolving — to become ever more complex and sophisticated, so this is naturally what we expect to find on archaeological sites. It upsets our carefully structured ideas of how civilizations should behave, how they should mature and develop, when we are confronted by a case like Göbekli Tepe that starts out perfect at the beginning and then slowly devolves until it is just a pale shadow of its former self.
