In that case every human being (be it Manmohan Singh, Sonia Gandhi or even myself) has no historic evidence beyond one's parents or grand-parents.
I mean there is no historical evidence of my grand-father because he is no more and he had no land in his name nor was he like Gandhiji/Ambedkar/Nehru etc. whose statues/films etc are historical evidences.
So does it mean that I do not exist because now I cannot prove that my grandfather died 35 years ago and was alive till then?
