....The whole issue is Ethnic more than anything, they ethnicities just happen to have different religions but the basic dynamic would be the same if it was two Muslim groups. The only real religious aspect is the tensions about Temple Mount (as Jews know) or Al-Aqsa (As Muslims do)
It's ethnic and rooted in the historic emergence of the ideas of nationalism, in the late 19th century and events that took place between about 1880 to 1948.
The history goes back more than two and a half thousand years, but the relevant history goes back to the latter decade of the 1800's and the decay of the crumbling Ottoman Empire.
This coincided with the origins of Zionism, the movement that grew out of the desire of displaced Jews, scattered across Europe, North Africa and the Middle East, to return to their ancient homeland.
Those Jewish communities had suffered discrimination and various pogroms for centuries.
The Turks were allied with the Germans and Habsburg Austrian-Hungarian empire, extending into WW1.
Britain wanted to secure the route to India and its eastern empire, through the Suez Canal and along with its Allies, France and Imperial Russia planned to drive the Ottomans out of the Levant.
The British enlisted the help of the various Arab clans and tribes to fight the rag tag Turkish forces, on the promise of handing over the land to form an Arab nation.
Meanwhile, Britain and France had other plans to carve up the region into newly drawn territories and rule them themselves.
Those territories became the basis of the subsequent Middle East countries that emerged later.
Following WW1, with the Turks gone, there was a gradual migration of European and Russian Jews to what was now re-named Palestine, to join the Jews that had always lived there.
Arabs and Jew lived side by side, although there was growing resentment from some of the Arabs , to the growing numbers of new settlers, who began to develop the landscape.
Following WW2, Britain and France gave up on their territories and with the mass migration of Jewish refugee survivors of the war in Europe, the state of Israel emerged.
You can read about that troubled birth for yourselves.
Note that even though the name Palestine has its roots in variations on ancient names, going back a couple of thousand years, there was no such thing as "Palestinians' until after the formation of the state of Israel.
It's a term that came to describe the displaced Arab people's, out of a population of some 500,000 or more, who both moved out of the region en-masse, or were driven out.
The present day animosity was born out of the Arab leaders not accepting the formation of the state of Israel and their failed attempt to usurp the newly formed nation in their 1948 war.
The newly formed UN and the Israeli's proposed what today would be called a 2 state solution, but the Arabs refused to accept it, as they have done at every attempt since.
The rest has been unfolding history.
Unfortunately, there has never been a political group, with enough power to be said to represent the Palestinians , who would accept a 2 state solution.
That possibility is now far beyond hope.
With the rise in Iran's power and influence and the deep hatred felt by many Palestinians, reconciliation looks impossible.
