First, the Jews are the only surviving people with an original claim to the land. The others - Philistines, Canaanites, Moabites, etc. - are all gone. Second, it's true that *many* Palestinians (hardly "most") are descended from Jews who converted to Islam only because life under Islamic rule was so harsh. But Arabs *have* been streaming into "Palestine" since the end of the 19th century, attracted to the economic opportunity brought on by the Jewish return. Moreover, when the British authorities restricted Jewish immigration in the 1930s and 1940s, they not only permitted but *encouraged* Arab immigration at the same time. One need only look at family names of many so-called "Palestinians" (not to mention the British censuses) to verify these facts.
