@aphanas,
You just make this **** up as you do along, don't you? There never was a language nor a script which was called mesopotamian. The Sumerian civilization dates back as far as 6000 ybp, and their written language as far back as 5000 ybp. Aramaic was not written before 3000 ybp at the earliest. Arabic does not appear as a written language until about the fourth century of the common era. It's pretty easy to make sweeping claims when you've got 4000 years to play with. Personally, i suspect that you're clueless, but that you're pretending to be knowledgeable.
