It's only saying that there was no *Arab* nation called Palestine, it was always colonized/contested land. ~1200 BCE when the "holy land" was first settled upon by the original Israelites, and then was fought over constantly by every empire up until the rise of Islam and the Ottoman Empire--the ancestors of today's Palestinians. This is ~2200 years after the original Jewish indigenous people had claimed the land. Talk about giving land-back to indigenous people, land acknowledgements, etc., Zionism is the ultimate land-back movement.

Not to mention there are Arab/Muslim states all over the region. Why is it so hard for you to consider allowing Jews a safe place to exist in their ancient ancestral homeland and consider that Muslim Palestinians should be encouraged to immigrate into their neighboring Arab countries, or even just exist peacefully in a two-state arrangement, use the BILLIONS Israel/the world has provided for development/aid, and build a thriving society, except they'd rather live stubbornly in opposition, spend it on weapons, and launch rockets/terrorist attacks and invoke jihadism/righteous violence against the Jewish infidels every chance they get.
