Oceanography research indicates that the bridge has been in existence for approximately 7,000 years.
The carbon dating results from beaches near Dhanushkodi and Mannar Island align with the timeline of the Ramayana.
The bridge was walkable until the 15th century. Records indicate it was above sea level until 1480 when a cyclone damaged it.
The bridge spans 50 kilometers, dividing the Gulf of Mannar and the Palk Strait.
Ram Setu goes by alternative names like Adam's Bridge, Nala Setu, and Setu Banda.
Ram Setu is considered both an archaeological and historical piece of evidence for the Ramayana.
Valmiki's Ramayana is the earliest known reference to the bridge.
As Shri Ram approached the southern tip of India, he sought assistance from Samudra dev to find a way to cross to Lanka.
Samudra Dev revealed that Nal and Neel, vanaras in his army, could make stones float when thrown into water.
The presence of floating stones and NASA images strongly support the historical reality of the Ram Setu bridge.
