In this part of the arab world, it is claimed that we (arabs living between Qatar peninsula and Musandam peninsula) originate from the arab Azd tribe that came from Yemen in the first century CE after the fall of the Marib Dam. In fact in arab myths, it is claimed that all arabs originate from Yemen.
false. The true non meme origin of arabs is not Yemen. Arabic originates from the north Arabia/South Levant area. It first started spreading from there to more regions in the middle east from the 1st to 3rd centuries AD. And then spread to wider areas after the Arab conquest. Also the first mention of Arabs was from Assyrians that claimed to have fought them, in northern Arabia. So the Arabs are definitely not from southern Arabia or the Yemen region. That is not to mention that Yemen had it is own south Arabian languages that aren't even from the same Semitic branch as Arabic. So I don't think Arabs are from Yemen. I think Arabs originate from Northern Hejaz/Southern Levant, you know? The area where Petra and Tabuk are. Probably.
