The narrative “Jews are colonizers who stole the land from Palestinians” is a factually false narrative.
Palestine never existed as a State
To start with, Palestine never existed as a state. They don't have coins, rulers, borders, history, etc. Arabs are very desperate to prove the contrary, but every time they try, they confirm that the land belonged to Israel.
Here are three examples:
An Arab woman is very proud to discover the word “Palestine” in a 1942 document. She thinks to prove thereby the existence of a State called Palestine, in fact, it designed only a region, not a State. Even during the British mandate for Palestine, all the artifacts (stamps, coins, passport, etc) mention Israel.
It was Adrian who changed the name of Judea-Samaria to Palestine, coming for the Philistines, enemy of the Jews. He wanted thereby to punish the Jews, who revolted against the Romans. Since then, the region became known as Palestine, but it never was a State. Actually the indigenous inhabitants were in fact the Jews living in Judea-Samaria.
Likewise, Pro-Palestinian use this map from the 1947 National Geographic to prove that a State called Palestine existed then, when again it was not a State but a region.
A Palestinians history books use a picture to illustrate the (non-existent) State of Palestine. When you dig further, you find out this picture actually describes a Jewish State.
The Jews didn't steal the land of Palestinians
Before 1948, the Jews bought lands from Ottomans and local Arabs. In 1948 Palestinians didn't accept the partition plan from the UN and were told by theirs leaders to leave Israel temporarily, and come back after the five Arab armies, who declared war with Israel, threw the Jews in the sea. However, Israel defeated the five armies and Palestinians who left became refugees.
There are many archaeological proofs that Jews are the indigenous inhabitants of that land
The Merneptah Stele and the Mesha Stele are both ancient inscriptions that provide proof that Israeli were the indigenous people of the Levant, but they differ in their origin, content, and the time periods they represent. The Merneptah Stele, dating to around 1208 BC, is an Egyptian inscription mentioning “Israel”, while the Mesha Stele, dating to around 840 BC, is a Moabite inscription that details King Mesha's victories over Israel.
