Nobody is asking you to be smart and read the books we read, just do an online search and read any book. There's no boundary between Arabs in Syria and other ethnic groups, it just happened that the Ghassassnah, the Syrians of the southern regions of natural Syria spoke Arabic due to their proximity with other Arabs. Today's political borders of Syria have nothing to do with the fact that Syria pre-dates the world in continuous civilization, your ignorance doesn't add much value either.
