Why do you think the KJV is the "original translation"? As far as English translations of Scripture go, it was preceded by the Wycliffe Bible. And a translation of the Gospels was produced in the Old English era.
While technically true this is somewhat pedantic, the KJV was the first vernacular translation to be widely available in the English speaking world and is a hugely influential text for literary English, so just take "original" here in a metaphoric sense.
