Consequently the civilizations of the world naturally and simultaneously started developing near the rivers which initially started flowing due to the melting of glaciers near the Equator e.g. When populations multiplied, these river waters became insufficient.Therefore some people started travelling from south to north.
Therefore the history of growth of civilization in the world is not 4 to 5 thousand years old but it is more than 10,000 years old.
Valmiki Ramayan contains graphic and poetic details of eight constellations during Hanuman’s return journey from Sri Lanka to Sunaabh Hill in the middle of the sea which apparently took about four and a half hours from AM to 11 AM.
All these details of planets and nakshtras with reference to eight constellations described in Sarga 57 (1, 2, 3) of chapter five tally exactly with the sky view generated by the software for the morning of 14th September 5076 BC from Lanka.
The story of Shri Ram‘s life was first narrated by Maharishi Valmiki in the ‘Ramayan’ which was written after Shri Ram was crowned as the king of Ayodhya, Maharishi Valmiki had a great sense of astronomy as he has made sequential astronomical references on important dates related to the life of Shri Ram indicating the location of planets vis-à-vis the zodiac constellations and other visible stars (nakshatras). Zodiac sign of king Dashratha was Pisces and his nakshatra was Rewati.
Needless to add that similar position of planets and nakshatras vis-à-vis zodiac constellations and the equinoxes is not repeated in 25690 years. This planetary position was prevailing on the 5th of January 5089 BC and it was on this day that Shri Ram had to leave Ayodhya for 14 years.
On the basis of planetary configurations described in various other chapters of Valmiki Ramayan, the date on which Ravana was killed works out to be 4th December 5076 BC and Shri Ram completed 14 years of exile on 2nd January, 5075 BC and that day was also Navami of Shukla Paksha in Chaitra month.
