text: Though it cannot be evidenced that this was something to do with Ramayana or not however considering the quality and details included in Ramayana it is very likely that author of Ramayana had seen some sort of connection between two which looks like bridge and that's why he would have included this in his books.\n\nSome Hindu groups claim that the bridge is evidence that events narrated in the Ramayana epic actually took place and cite NASA's imagery of it as proof of their claims. NASA has distanced itself from such claims:\n\n    "The images [...] may be ours, but their interpretation is certainly not ours. [...] Remote sensing images or photographs from orbit cannot provide direct information about the origin or age of a chain of islands, and certainly cannot determine whether humans were involved in producing any of the patterns seen."\n\n\nArcheological studies of the bridge are ongoing, and some archeologists claim to have found evidence suggesting that the bridge is man-made. For instance, some researchers from Bharathidasan University, Tiruchirappalli, announced that the "bridge" is only 3,500 years old.\n\nSea levels rose about 10 or 20 metres in the 6th millennium BCE to reach levels similar to today, so in 6000 BCE the bridge would have been an isthmus situated above sea level. As such, it almost certainly would have been a viable route for humans to have reached Sri Lanka by dry land.
