There was never a country called Israel until 1948. It was always Palestine.

The idea of a nation called Israel is the invention of Zionists in the 19th and 20th century.

Ancient Israelites existed approximately 2000 years before your incorrect claimed timeline. Today’s Jews are descendants of Israelites.

It is also trivially simply to disprove “It was always Palestine”. It was made up by Romans. Again, much later than when Jewish people lived there.

And spearheaded by the Haganah and Irgun, who were violent terrorists whose many bombings "persuaded" the British to hand the land over to them.
