NASA Images Discover AncientBridge between India and SriLanka (Courtesy : NASA Digital Image Collection)
Space images taken by NASA reveal a mysterious ancient bridge in the Palk Strait between India and Sri Lanka. The bridge currently named as Adam´s Bridge is made of chain of shoals, c.18 mi (30 km) long.
The bridge´s unique curvature and composition by age suggests that it may be man made. The legends as well as Archeological studies reveal that the first signs of human inhabitants in Sri Lanka date back to the primitive age, about 1,750,000 years ago.
This information is a crucial aspect for an insight into the mysterious legend called Ramayana, which was supposed to have taken place in Tredha Yuga (more than 1,700,000 years ago).
In this epic, there is a mentioning about a bridge, which was built between Rameshwaram (India) and Srilankan coast under the supervision of a dynamic and invincible figure called Rama who is supposed to be the incarnation of the supreme.
This information may not be of much importance to the archeologists who are interested in exploring the origins of man, but it is sure to open the spiritual gates of the people of the world to have come to know an ancient history linked to the Indian mythology.
