does it really matter if it is Ram setu? What if god himself descends down to say that it is the same Ram setu - will u start worshipping it? According to Ramayan, the stones used to float on water- then how come they are submerged? Why cant this be taken as a geographic feature like mountains or deserts?

If NASA did say the structure was man made and 175000 yrs old, it would have been a bigger news than cancer cure and the structure would have easily beaten pyramids as greatest/oldest man made structure.

Try to look at it the other way around- it is possible that many centuries back, the 'setu' or this stone road used to be above sea level and it was brought down by sea waves or cyclones etc. The sighting of this  somehow found its way in our epic.

i agree to sikand's openion. i'd a great respect to RAMA but it is yet to prove that there was some bridge b/w india and srilaka. we shouldn't live in imaginary world. let's collect facts to prove it first.

NASA has not confirmed any such thing. It's satellite has provided the photos, that's all. The interpretations are of news channels who are only interested in their TRP and not the truth. News channels are quite capable of repeating a lie 100 times in a day which we start believing as the truth.
