To those that say that Palestinians lived in Israel for centuries are greatly mistaken look at the facts: 

The term "Palestine" is believed to be derived from the Philistines, an Aegean people who, in the 12th Century B.C.E., settled along the Mediterranean coastal plain of what are now Israel and the Gaza Strip. In the second century C.E., after crushing the last Jewish revolt, the Romans first applied the name Palaestina to Judea (the southern portion of what is now called the West Bank) in an attempt to minimize Jewish identification with the land of Israel. The Arabic word "Filastin" is derived from this Latin name.3 

The Hebrews entered the Land of Israel about 1300 B.C.E., living under a tribal confederation until being united under the first monarch, King Saul. The second king, David, established Jerusalem as the capital around 1000 B.C.E. David's son, Solomon built the Temple soon thereafter and consolidated the military, administrative and religious functions of the kingdom. The nation was divided under Solomon's son, with the northern kingdom (Israel) lasting until 722 B.C.E., when the Assyrians destroyed it, and the southern kingdom (Judah) surviving until the Babylonian conquest in 586 B.C.E. The Jewish people enjoyed brief periods of sovereignty afterward before most Jews were finally driven from their homeland in 135 C.E. 

Jewish independence in the Land of Israel lasted for more than 400 years. This is much longer than Americans have enjoyed independence in what has become known as the United States.4 In fact, if not for foreign conquerors, Israel would be 3,000 years old today. 

Palestine was never an exclusively Arab country, although Arabic gradually became the language of most the population after the Muslim invasions of the seventh century. No independent Arab or Palestinian state ever existed in Palestine. When the distinguished Arab-American historian, Princeton University Prof. Philip Hitti, testified against partition before the Anglo-American Committee in 1946, he said: "There is no such thing as 'Palestine' in history, absolutely not."5 

Prior to partition, Palestinian Arabs did not view themselves as having a separate identity. When the First Congress of Muslim-Christian Associations met in Jerusalem in February 1919 to choose Palestinian representatives for the Paris Peace Conference, the following resolution was adopted: 

We consider Palestine as part of Arab Syria, as it has never been separated from it at any time. We are connected with it by national, religious, linguistic, natural, economic and geographical bonds.6 

In 1937, a local Arab leader, Auni Bey Abdul-Hadi, told the Peel Commission, which ultimately suggested the partition of Palestine: "There is no such country [as Palestine]! 'Palestine' is a term the Zionists invented! There is no Palestine in the Bible. Our country was for centuries part of Syria."7 

The representative of the Arab Higher Committee to the United Nations submitted a statement to the General Assembly in May 1947 that said "Palestine was part of the Province of Syria" and that, "politically, the Arabs of Palestine were not independent in the sense of forming a separate political entity." A few years later, Ahmed Shuqeiri, later the chairman of the PLO, told the Security Council: "It is common knowledge that Palestine is nothing but southern Syria."8 

Palestinian Arab nationalism is largely a post-World War I phenomenon that did not become a significant political movement until after the 1967 Six-Day War and Israel's capture of the West Bank. 

Even a leading Arab nationalist believed the return of the Jews to their homeland would help resuscitate the country. According to Sherif Hussein, the guardian of the Islamic Holy Places in Arabia: 

The resources of the country are still virgin soil and will be developed by the Jewish immigrants. One of the most amazing things until recent times was that the Palestinian used to leave his country, wandering over the high seas in every direction. His native soil could not retain a hold on him, though his ancestors had lived on it for 1000 years. At the same time we have seen the Jews from foreign countries streaming to Palestine from Russia, Germany, Austria, Spain, America. The cause of causes could not escape those who had a gift of deeper insight. They knew that the country was for its original sons (abna'ihi­l­asliyin), for all their differences, a sacred and beloved homeland. The return of these exiles (jaliya) to their homeland will prove materially and spiritually [to be] an experimental school for their brethren who are with them in the fields, factories, trades and in all things connected with toil and labor.16
