You guys are confusing one thing here.....
Urdu is not widely spoken in India!......this does not mean that Urdu did not originate in India.
Tell me, how many Indians speak in Sanskrit today????
Like all the religions of the world has their roots in Hinduism......almost all the languages of the world has their roots in Sanskrit......and Urdu is no exception......Therefore Urdu is bound to have Indian origin........
AND these are not my words.......great Historians,Writers,Scientists,Philosophers from all over the world says this.....
Mark Twain, American author: "India is, the cradle of the human race, the birthplace of human speech, the mother of history, the grandmother of legend, and the great grand mother of tradition. our most valuable and most instructive materials in the history of man are treasured up in India only."
Will Durant, American historian: "India was the motherland of our race, and Sanskrit the mother of Europe's languages".
Sir William Jones, British Orientalist: "The Sanskrit language, whatever be its antiquity is of wonderful structure, more perfect than the Greek, more copious than the Latin and more exquisitely refined than either."
Sir Monier-Williams (1819-1899) Orientalist, professor of Sanskrit at Oxford in 1860, wrote: "The Panini grammar reflects the wondrous capacity of the human brain, which till today no other country has been able to produce except India."
Ever heard of INDO-EUROPEAN languages? yeah, the're languages native to the indo-europe region. There include English, Dutch, German, Swedish, Finnish, Italian, French, Spanish, Latin, Greek, Persian, Afrikaans, Sanskrit, Urdu, Hindi, Bengali, Gujarati etc But NOT Arabic, Hebrew, Malaysian, Indonesian, Japanese, Chinese, Korean, Tamil, Malayalam, etc.
Sanskrit, as ancient Greek and Persian, and the mother tongue of Latin (not Latin herself tho) are SISTER languages. The language which derives these ancient languages is called (or the proposed name for it is) "Proto-Indo European" The people who spoke this language are known as Proto Indo Europeans. Yeah, that's right, our "ancestors", but not the ancestors of Arabs, Chinese, Japanese, African people etc.
Also, Semitic/Abrahamic religions actually have no proved link to Hinduism/Buddhism, so that the "all religions derived from hinduism" claim is dead wrong.
Just because some popular writers/jokers/philosophists claim something, it does not necessarily mean it is. Ask a historian, or a linguist, not these peeps
It's worth a read bro:
