So the logic is Judaism was born in Palestine and hence Jews have a right to all of Palestine. Well going by that logic Zoroastrians should take back Iran and kick all the Muslims out, it was the birthplace of Zoroastrianism after all. And more so because they moved out of Iran because of the Muslim invasion, unlike the Jews who were ousted from Palestine centuries before the Arabs conquered the Palestine.
Buddhists should get hold of India btw, the birthplace of their religion.
If you are referring to the land as the birthplace of a group of people called Jew, then Cherokee, Shawnee and Huron should get most of the North American east coast, the birthplace of their people. Most British with Saxon blood should go to Germany and demand their share. Hell these are all historical events that are much more recent than the Jewish ousting from Palestine.
You can't build a case on the logic that because this group of people were living here 2000 years ago they have a right to the land. What about the right of the people that have been living there for the past hundreds of years?
Its not just a matter of Muslim or Non-Muslim, whether Jerusalem is holy place or not, its an issue of basic human rights. You can't just uproot communities living their for hundreds of years based on your religious scriptures. .
