Let me make clear to the Centre, that faith does not need any type of evidence. If I have only the faith, then I can be a fool, but crores of people having a faith on Lord Rama cannot be fool. In large scale of faith, exceptions are not counted. When a new born baby starts growing up, and starts calling mum, and papa, then how he comes to know this is his or her papa. Obviously Mum says that he is his or her papa. Once Child becomes mature, whether he or she ask from mum to get the DNA test of so called Papa to prove himself as Papa. Obviously not, he or she has a faith on mum.
