The war here began because some people in Europe, based on their holy book, decided they had the right to move to someone else’s country and take it by force. That’s the reality of how Israel was founded - it’s completely unreasonable to expect the Palestinians to accept that they should be kicked out of their ancestral homes because some people in Europe claim god gave them superior rights to that land.
The jews have the longest continuous claim to the land of modern day Isreal, as well as parts of modern day Syria, Jordan and Egypt that anyone in recorded history. The Caananites have an older claim but anyone with Caananite ancestry likely doesn't know it because they disappeared/were wiped out thousands of years ago.
The jews were "given" Isreal because of the Nazi holocaust and the realization that without a proper homeland they'd never be free from genocide/ethnic cleansing/pogroms/etc. Though, that's not really held true anyway.
When deciding who is evil, and who is righteous, a simple test will settle the question. If one side were to unilaterally disarm and seek to live peaceably, how would the other side react? The side that would choose peaceable coexistence is the righteous side. The side that would kill everyone on the other side is the evil side.
And if you would conclude the Palestinians would be the righteous side you are so incredibly delusional that polite conversation on the topic is simply impossible.
