However, I do not find any thing wrong in the statement - "No proof of Ram".
There are two worlds - spiritual and material. If you decide to live in spiritual world, you should believe Ram existed. You should also be a vegetarian, marry at 25, follow Brahmacharya till then, not watch TV or music (Brahmachrya - remember?) or have sex and go to forrest after 50.
you cannot have best of both the worlds. If you chose to live in material world (which we all do) we have to go by the laws of land - Sampoorna Ramayana is not a proof admissible in the court. Nor are handed over mythology stories. It is a known fact that Ram's existence is not established, do not go in tizzy fighting over it.
Moreover, as a hindu, I know that Ram was a Hindu follower, a born Hindu, not a founder of Hinduism. Where is the clash in buiding a new project? In India, every village had some pandavas visiting them, Feet of Hanuman imprinted, Parvati's (Sati's) body parts dropping when Shiv performed Tandava etc, etc. So should we stop all projects? Be reasonable and not fundamentalists. Same idiots will now turn to another forums and call others (muslims, sikhs, christians etc) fundamentalists.
