Oh for god's sake!! isnt there anyone from Tamil Nadu here?? Because, they all know about Ravan and Ram and even many Tamil literary works talk about them.. Sri lanka, India, Rameswaram and the other places are all found in Tamil Literature and the best part is that it co incides exactly with valmiki's Ramayana and there is geographical Proof too.. IF thats not a Bridge, Then What is it?? but of course it was not built by monkeys and animals but Ram's Army and Ram must have been a Powerful Emperor at that time.. You have the Trojan War in Greek mythology.. Where Agamennnon and co went to rescue Helen.. Its somewhat similar to that.. only difference is that Ram lived long before that and At that time, India was the only super power in the world which even Alexander the Great could not invade through..
