Answer 2

It is impossible to pinpoint where the Aryan language came from (actually, Aryan is a family of languages) but this statement is likely to be broadly true. 

One of the most ancient of the Aryan languages is Old Persian, examples of which have been found in what is now Iran, Romania (Gherla), Armenia, Bahrain, Iraq, Turkey and Egypt. During the last twelve years Old Persian tablets have been unearthed. These suggest Old Persian was a written language, used for keeping records.
