I see from your posts that you are a faithful follower of Karunanidhi and his selective aethist ideas and other related rubbish. What will the Government lose if the canal is rerouted? Saying that there is no evidence for Ram and Ramayana is not the issue. One can give innumerable examples from other religious scriptures to question the very faith of those religions. The point here is whether the Government will respect the sentiments expressed and agree to reroute the canal. This it is unwilling to do for fear of antagonizing MK, the Senile Old Man of the South, who is bent upon humiliating Hindu beliefs as much as possible. And with people like you to support him, he may well succeed.
