we can show proof for existence of Jesus and Buddha.Because they were recent.and Christianity ,Buddism etc are new religions but hinduism and hindu mythologies not new ,no scientist can say exact age of vedhas ,yoga ,Geetha ,Maha bharat or Ramayan.
Don't ask proof for everything.Rulers of Centre and TN State are not Hindus.so they are creating this type of noisy.if centre says No evidence to prove existence of Ram then why r u making noisy in ayodhya issue.Built Babri masjid there.can u dare for that.
