Maya monuments had been built and inscriptions depicting their deities recorded, considerably pre-dating the 1st millennium BC. The close resemblance to Ravana times. And this Mesoamerican civilization began in situ is never contemplated.
Noted independent reseacher and author John Major Jenkins note as "The early Maya astronomers who created the Long Count calendar some 2,100 years ago intended the end of the 13- baktun cycle of the Long Count (December 21, 2012) to target the alignment of the December solstice sun with the plane of our Milky Way galaxy (
plane of our milky way galaxy = galactic alignment <--My note).? But these hypothesis are not accepted by some Mayan researchers.
The Maya clearly stated that the 2012 end date involved two phenomena, i.e., a solar shift, Venus transit and mounting earthquakes. The Mayan calender was based upon "synthetic numbers" that had 13 as the seed number, which were used to carefully measure and track the solar year, the synodic periods of Venus, Mars, and Mercury as well as to tabulate much longer cycles. Nonetheless, the prime cycles were the sacred/solar year ( Sun cycle, a period of 5,125 years.)
, synodic periods, and realigning these with Venus was the real focus of the 104-year Venus Round.
NOTE--- The majority of the Maya codices were burned by Europeans like Bishop Diego de Landa during their conquest of Mesoamerica and subsequent efforts to convert the Mayan people to Christianity. (Please read also our UHO article on the Portuguese crimes)
Ofcourse we are not going to formulate a theory that all of our ancient Hela Technology comes from the Aliens. It will be very injusty to our Hela entity and to it’s material and cultural legacy. May be this technical and scientific ability would have upgraded by Hela people themselves for the millennias without help of someone from outside (hereby meaning “Aliens”)
We have very good reasons to suspect that our ancient Hela comunity was belonged to the Scientifically advanced civilization. The Hydro- technolgy used for the constructing of the Mipilimana tank is very impressive. This Mipilimana tank belived to be constructed about in 3000 years ago. This scientific knowledge of our Hela people was progressively get lost as ancient Hela civilization became weakened by corruption and was repeatedly overrun by foreign invaders. And this Hela civilization might been erased from history by some global catastrophe. (like recent Tsunami).
I think that we need to be informed and studied about the "whole Concept" and not leading us only on few hypothesis. For further ground studies I like to point out some places , on where we could find some Pro or Cons evidences on our approach. 1-Rumassala (Galle)- noted for gravity variations and strange compass bearings.
2-Sakawala Chakraya ( Anuradhapura)
The outer circle also seem as the principal celestial cycle. and It may gives some evidence that Sakwala Chakra design may be an astronomical map. The figures of fish and other animals may symbolize the constellations and whole outer circle can be considered as their precessional cycle.
3- Sita eliya (Hortan plains)
4- Ravana kotuwa ( Hambantota/ Yala sea). Belived to be Ravana's capitol and now lies under the sea.
About 200 million years ago, geologically Sri Lanka was linked with India, Madagascar, Australia and Antarctica, in a land mass known as Gondwana. Sri Lanka separated into a land mass known as Lanka Dvipa (Island of Lanka), and part of the land submerged into the sea. This seismic happening is confirmed by modern science. According to some scientists, world faced instant and terrible sismic, Tsunamis and flood effects around in sometime 10500 BC--5000BC.
