I believe spiderman, superman and heman also. Is there any evidence of spiderman or above mentioned Ram. Not a historical truth. Merely a story. Mythology cannot be science. If Ram can build sethu then why his country needs foreigners to build bridges or boeing to supply vimanas. Where is Ram's technology lost?
Hindus still travel by bullock carts, camel carts when their mythological ancestors were using vimanas and super jets. Hinduism is totally baseless and unscietific. It was penetrated by aryan migrants to suppress aborginal dravidians.
