Nope, Canaanites have existed along side with Jews. So called Palestinians have never existed.
Forgive my ignorance but what was Palestine before the creation of Israel? A country and therefore an ethnicity? I understand the Topic of Palestinians is not a popular discussion point among Lebanese and for good reason but they are a people and they had a country and genetically they are very close to Lebanese... if you want a fake people look at all the Jews that are not Mizrahi Jew... mizrahi jews are the only real Jews
