It says "other theories" want to point to Arabia as the origin of the semitic languages.
It has nothing to do with Arabs being one people, Hebrews another people, Akkadians, Baylonians, Assyrians, Persians, and all others being different people with different languages and culture and creating their history on the land where their history is known for.
You keep assuming that Jews are only the Hebrews when in reality they are a conglomeration of peoples who lived there in the area and became Jews, like the
Jebusites who were defeated by King David. And any who converted to Judaism afterwards.
No Study anywhere says that all people and all languages in that area have an origin from Arabia or from Arabic.
Your comparison is total nonsense.
Where EXACTLY from your link, does it say that Arabic is the original, mother tongue of all of those people and eventually it branched out into all of those languages?
Sure some others want to claim the Arabian Peninsula as the origin of Semitic languages, but there is no evidence of that.
Nothing compared to the whole city we have of Canaanite Jericho.
And YES, there is one original semitic language, and that means all those speaking variants of that original Semitic language are most likely descendant from the original race.
That not only is almost always true, but we are sure that is true with Canaanites, Babylonians, Akkadians, Assyrians, Phoenicians, Philistines, Edomites, Amorites, Edomites, Hebrew, etc.
They are all the same race originally.
But is NOT true of Persians, who are not Semitic.
Jews do not encourage conversion and do not encourge intermarrying.
But clearly I am saying the current Jews are NOT the original Hebrew.
I am saying the original Hebrew were Arabs, looked like Arabs, and sounded like Arabs.
However current Jews do NOT look like Arabs, have much whiter skin, and do not at all sound like Arabs, having the Germanic Yiddish as their native language.
All studies say that Canaanites, Babylonians, Akkadians, Assyrians, Phoenicians, Philistines, Edomites, Amorites, Edomites, Hebrew, etc. are all related because they all spoke a derivative of the same Arab language, which is Canaanite originally.
And the original Semitic language is NOT Arabic or from the Arabian Peninsula.
The origin of the Arabs is the Levant and the original language is Canaanite.
