tldr version of history for you:
ottomans conquered the area of land referred to as Palestine/Israel over 600 hundred years ago, (during which time the people nor the area was never referred to as Palestine until the end of the 19th century when some of the population started calling themselves Palestinians in a bid for independence from the Turks); and held that piece of land until the fall of the Ottomans after the First World War, after which the French and English split up the land, during which time the English fucked over the arabs in the area (big surprise they did it to everyone).
Meanwhile in the West, since campaigning since the 1800s to be given back the land that was 'stolen', something most educated adults refer to as conquered, from the jews by the Italians (aka romans), after which they had spent 2000 years nationless (in a manner similar to what has happened to the Palestinians except much more severe, as Israel is the only jewish nation) and being periodically persecuted in whatever nation they resided in. this culminated in the Balfour declaration, and the mass movement of jews to Israel.
Due to the historical differences between jews and arabs there was conflict and Britain retained the right to manage Israel. until the Europeans decided that the land should be partitioned causing a 'civil war' between Israeli and Palestinian militias. Surrounding nations decided to join after the establishing the State of Israel, escalating the war to an Arab-Israeli conflict.
Jews won the war. so tell me, when was it stolen?
also i realise how much of a waste this is after looking at your comment again.
