The Jews never had to come back as they were given the land by the Persians thousands of years ago There were no Palestinian "people" the area was know as Yehub Medinata (Jewish Province) The land where the Jews live
The Palestinians appear to be immigrants from other countries in the Middle East some of them Bedouin,
So although there are a myriad of stories about the area and the people your version is IMHO totally without foundation
