See the only problem is that your field of research is only limited to japheth which I think is great especially when research the practical application in history.. but if you look at the history of other family lines like kush and the rule that stretched from nubia to india or the phoenicians who was canaanites also phuties from puntland. Chinese are originally known as sinites.. original Hindus was kushite also these hametic nations founded mesoamerica and the olmecs. Nonetheless these nations had their own beliefs and didnt accept the hebrew belief but weirdly enough they retain their biblical name just we are seeing now with japheth. They just as hamites have their own perspective on what happened after the flood
