if what you are saying is right, it is not a prove that there was no other language older than arabic, for your information my friend the oldest known language is the sumerian and akadian languages and there is no prove until today in archiology that arabic is the oldest or it is the origin of languages i myself and my father and mother and all my relatives in iraq speak one of the oldest languages in the world that is the chaldean language a branch of the aramaic language used widely in the middle east before islam and for your information again arabic is one of the languages branched from the aramaic language just like hebrew language thank you ammar khidhir kalasho
