Not quite----most of the languages you mention have nothing to do with the land of Canaan. ----the only surviving language that developed in Canaan is Hebrew.Wrong.
The oldest known human metropolises in the world are in the Land of Canaan.
All anthropologists know that the location of the source of all Arab Semitic languages is the Land of Canaan.
Arabic is just one of the many Arab Semitic languages, and not the oldest.

Speakers of East Semitic include the people of the Akkadian Empire, Ebla, Assyria, Babylonia, the latter two of which eventually switched to East Aramaic and perhaps Dilmun. Central Semitic combines the Northwest Semitic languages and Arabic. Speakers of Northwest Semitic were the Canaanites (including the Phoenicians, Punics, Amorites, Edomites, Moabites and the Hebrews), Arameans and the Ugarites. South Semitic peoples include the speakers of Modern South Arabian languages and Ethiopian Semitic languages.

The rest developed in some other lands of the Levant.
