Give me an example of Palestinian culture. What language do Palestinians speak? Where are their cultural monuments?
They speak a dialect of Arabic. Various religious sites like Bethlehem are part of their cultural heritage.
Additionally, if Palestine has never been a state, by what right or standard do you deem Israeli land to be "Palestinian"?
Reread what I wrote, I'm just using the term that has historically referred to the region that encompasses Israel and the occupied territories even by Zionists. I'm not saying Israeli land is Palestinian land though they do have something of a claim to it given the fact they lived there continuously for generations until being ethnically cleansed by Zionists.
And if there has never been a Palestinian state, why do so-called Palestinians want one now?
Because they were promised one and the interwar period set up the standard of national self determination. That standard didn't exist when most of the world lived under premodern empires like the Ottoman state but that doesn't mean that the nations that came to claim that right didn't exist.
And if Palestinians really are Jewish, Christian, and Muslim, why couldn't Israel be considered the Palestinian state? Which Jews are Palestinian and which aren't?
Again reread what I wrote because I have been clear. If they are Jews that have familial roots in historic Palestine predating Zionist immigration then they are Palestinians. If they are Jews whose descendants came from Russia or Poland, as many Zionists did, then they are not Palestinian but rather Ashkenazim Jews
Again, please provide specifics. Are you suggesting that Jerusalem is and always was a part of "Palestine", and not Israel?
Not always since it was a part of the ancient Kingdom of Israel but Israel hasn't existed for thousands of years and for some time before the rise of the Zionists Jerusalem was seen as part of a region known as Palestine.
Again, what is/was Palestine? What were its borders? You have yet to explain what Palestine was, or what made it Palestine.
I did explain it though, you;re just ignoring my explanation
At the minimum the term referred to the administrative unit centered in Jerusalem but was also used as a general term for the holy land which encompassed an area around that administrative unit as well.
Historic Palestine is somewhat nebulous but in the 19th century referred to the area from the Eastern Mediterranean shore to the Jordan River and north of Rafah to the Litani River(now in modern Lebanon).
You said he revolted and failed. You can't be the head of a state that never existed.
He was the head of a de facto state, do you know what de facto means? Means it existed in reality but not nominally on a map. His attempt at a de jure state, one recognized internationally and nominally independent of the Ottomans, failed but he nonetheless ruled autonomously for decades under nominal Ottoman rule.
So there has never been a head of state, correct?
There was Yasser Arafat who headed the PLO, the internationally recognized representative of the Palestinian people. But no, he wasn't a head of state in the sense that the term is usually used. But I think you are far too hung up on that, as I said a state requires a head of state but not a nation such as the Palestinian nation.
There is no evidence of a historic Palestine. Its history isn't nebulous. It's non-existent.
Its there if you are willing to step outside the rigid paradigm you view history within. Nations and regions exist even when there isn't a state there plastered with their name.
Historical Israel predates the 19th century by millennia.
Sure but it didn't exist continuously and hadn't existed for thousands of years. The Jews left Palestine and settled elsewhere. The modern state of Israel has only the most faintest of connections with the ancient Kingdom of Israel. There was also an Babylonian state as well in ancient times but no one recognizes the legitimacy of a Babylonian state in the 21st century just because of that.
What do you mean by "zionist"?
People who believe in Jewish nationalism and the right of the Jews to a homeland in historic Palestine.
No. Let's use your definition. The nation of Israel.
That's also recent and predated by the notion of Palestine.
