If your beleif is truthful, they are saved themselves, no one need to save. If it is not truth, it will die as time goes. e.g., people beleived centuries that earth is flat, or sun rotating around arth etc.. did they became as they beleived or beleif changed as they are? same will happen, if Ramayana is story it will be story, if not someday someone will prove.
Sometime back I read in Competetive Success(I ma sure you can refer to may other
hostorical books), a magazine that many Group 1 exam takers prepare had secion on
persons Past, mentioned Jesus 4B.C Budha ~500BC Mohemmed ~500AD there they showed
Valmiki ~800BC and Vedavyas ~800BC as Sanskrit poets, who wrote stories, why didn;t this
agitation takes place then? You know more thing Valmiki is contemperor of Ram as per
Ramayana... i.e Valmiki wrote part of Ramayana as they lived in same age. how is it
possible one who lived 170000years back and one who lived in 800BC can be contemperors?
