Arabic, the oldest language?

The Ahmaddiya website claims Arabic is the oldest language.

It is all of a piece - claiming Allah the only true God, Islam the first religion, the first man (Adam?) a Muslim, Mohammad the greatest man, and now - Arabic the first language (that it is the greatest language is a given to Muslims). Not to forget, Mecca the centre of the earth! I think Islam causes megalomania in its adherents.
