On Carvajal's account, therefore, not only did the Amazon have cities but its cities were comparable in size to those of Europe at the same time. He … - Graham Hancock

If ever a society could be said to meet all the mythological criteria of the next lost civilization – a society that ticks all the boxes – is it not obvious that it is our own? Our pollution and neglect of the majestic garden of the earth, our rape of its resources, our abuse of the oceans and the rainforests, our fear, hatred and suspicion of one another multiplied by a hundred bitter regional and sectarian conflicts, our consistent track record of standing by and doing nothing while millions suffer, our ignorant, narrow-minded racism, our exclusivist religions, our forgetfulness that we are all brothers and sisters, our bellicose chauvinism, the dreadful cruelties that we indulge in, in the name of nation, or faith, or simple greed, our obsessive, competitive, ego-driven production and consumption of material goods and the growing conviction of many, fuelled by the triumphs of materialist science, that matter is all there is – that there is no such thing as spirit, that we are just accidents of chemistry and biology – all these things, and many more, in mythological terms at least, do not look good for us.

If we impose on a map of the earth a 'world grid' with Giza (not Greenwich) as its prime meridian, then hidden relationships become immediately apparent between sites that previously seemed to be on a random, unrelated longitudes. On such a grid, as we've just seen, Tiruvannamalai stands on longitude 48 degrees east, Angkor stands on longitude 72 degrees east and Sao Pa stands out like a sore thumb on longitude 90 degrees east — all numbers that are significant in ancient myths, significant in astronomy (through the study of precession), and closely interrelated through the base-3 system.
So the 'outrageous hypothesis' which is being proposed here is that the world was mapped repeatedly over a long period at the end of the Ice Age — to the standards of accuracy that would not again be achieved until the end of the eighteenth century. It is proposed that the same people who made the maps also established their grid materially, on the ground, by consecrating a physical network of sites around the world on longitudes that were significant to them. And it is proposed that this happened a very long time ago, before history began, but that later cultures put new monuments on top of the ancient sites which they continued to venerate as sacred, perhaps also inheriting some of the knowledge and religious ideas of the original navigators and builders.

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.
