How do you prove existence of any ancient person. In old days, there were no cameras or audio recorders. Written documents on leaves with natural inks are unlikely to survive for so long unless preserved very well. It is only biographies written by sages that survived because they must have been re-written thousands of times by many writers down the ages. Inidians do not bury their dead that you might have the possibility of exhuming the body. Cremation by fire also leaves no proof.
Can any one of you bring proof of your grandfather's great grandfather? Some idiot is asking for proof.
