Man's civilizing efforts, as detailed and very advanced though they have been at certain times, have been interrupted, quite abruptly, by natural seismic occurrences on our planet. Entire continents moving thousands of miles in a period of a few days can produce earthquakes more severe than anything Richter has been working on as a scale! Between five and 25,000 years seems to be the interval between these seismic reapportionments of the Earth's land masses, wherein the entire crust slips into a new position on the underlying magma of the planet. Every part of the world is affected by such an event.
76000 - 24000 B.C. Lemurian
22500 - 8500 B.C. Atlantean
The nation of Poseid was inventive far beyond the wildest imaginings of modern scientists. Their fantastically advanced technology afforded consummate leisure, comfort, and a vast abundance of material things. Unfortunately, the people were much too preoccupied with the pursuit of physical pleasures and with the accumulation of luxurious possessions to take advantage of the opportunity to attain citizenship, and this shortcoming ultimately resulted in their downfall. Internal conflict arose when large numbers of Katholis (overly idealistic) deserted their cities in South and Central America and migrated to Poseid in order to escape their savagely warlike neighbors. The Katholi priests set about to bring Poseid under their sway, but they only succeeded in destroying the governmental and economic system which produced the wealth and luxuries they sought to usurp. Civil and religious warfare vexed the land until it submerged beneath the ocean waves.
When Atlantis sank in a localized earthquake, it left all the rest of the globe impoverished so far as technology was concerned. Nobody else knew how to duplicate that technology; so many of the things that had been used world-wide simply didn't exist any longer. Even though technology gradually diminished in the rest of the world, they managed to be civilized towards one another. But then 3,000 years after the sinking of Atlantis came a world-wide reapportionment of the land masses.
5500 B.C. Osirian and Rama Nations:
The pre-dynastic Egyptian culture was concurrent with the Rama Empire and both were concurrent with the end times of the Atlantean civilization. They were known as the three kings. Atlantis was predominantly a very practical group of people. The people in the Rama Empire of India were much more idealistic than they were either practical or mentally oriented. The Osirian nation was primarily noted for its use of mental techniques in a positive way.
The ancient Rama Empire in India became the fourth-ranking civilization under a dynasty of enlightened leaders who for a period of several centuries suppressed the priesthood. The Rama regime and predynastic Egypt had both managed to salvage some of their culture after the fall of Atlantis, but the rest of the world was reduced to a condition of brutal struggle for survival. The colonies of the world were irretrievably shut off from the technology of Atlantis, and in a few generations they reverted to a stone age-existence. The few manufacturing facilities not destroyed by world-wide earthquakes and tidal waves soon deteriorated from lack of raw materials to feed them. Stone replaced smelted metals for tools, and all too soon subsequent generations couldn't believe anything other than stone had ever been used. Egypt and India were precariously spared from the far-reaching upheaval, and their weakened governments gradually succumbed to evil priests and war lords.
That last reapportionment 7,500 years ago put an end to the Rama Empire in India as well as the Osirian nation in the Mediterranean basin. Today, what we consider ancient history only goes back to about that cataclysm. What we commonly refer to as the "cradle" of civilization in the region of the Tigris and Euphrates Rivers of today, was people coming back to some semblance of civilization and culture.
