I'm going to assume you are not actually denying the history of the Jewish people in Israel, so why, do you think, it isn't their land? And their Temple?
Some of the inhabitants of ancient Palestine were monotheists, but most of them were pagans.
I am reading at the moment "The Bible Unearthed" by Israel Finkelstein, he does not use the word "Jews", he uses the word
Judahites, and he explicitly says that these Judahites were the predecessors of Christians, Jews and Muslims.
The Judahite Temple was just another pagan Temple, the King David was just a local war lord that controlled only a little village.
Israel and Judah were two separated Kingdoms, and Israel was a pagan Kingdom.
Judah was an insignificant piece of land, nobody bothered to conquer it.
Israel was prosperous, but it was a pagan Kingdom.
After Israel was destroyed in 720 BCE by Assyrians, Judah was flooded by refugees from the North, and only after that the priests of Jerusalem began to promote the Yahweh-based monolatry cult.
They supported the King Hetzekiha, and Hetzekiha tried to ban the pagan cults. At this time, in order to support Hetzekiha and unite the people, the priests invented the legends about Israel and Judah being one people with common roots.
There were already a lot if legends, and some of these folklore became the "common history" of the conquest of Canaan and the supposed Kingdom of David, that never existed, because David only controlled a small village, according to archeologists.
The king of Judah Josiah also promoted monotheism, and he even tried to conquer Israel at the end of the 7th century BCE, when Assyrian Empire collapsed.
And at this time Josiah's court promoted the idea that people of Israel and Judah were of the same origin, but Israel was presumably punished by Yahweh, because they abandoned monotheism.
In reality Israel was a totally different pagan state, populated by totally different people, there was no common history with Judah.
The efforts of Josiah were not successfully, because the Egyptian King Necho decided to support Assyrians.
Josiah was killed, and Judah became a province of Egypt.
But the invented common history of Israel and Judah were already put into writings, that was the beginning of the Bible, a book of oriental fairy tales.
The Assyrian war was eventually won by the Babylonian faction.
In 597 BCE Jerusalem was plundered, ten years later it was totally destroyed and the priests and other members of the monotheistic elite were deported to Babylon.
In Babylon the expelled priests went on writing fiction stories about the monotheistic and Yahweh chosen people of Israel, but the majority of Palestinians remained pagans.
Monotheism became popular in Palestine after the split in the original monotheistic dogma, speak after the birth of Christianity. Many Palestinians became Christians, and later most of them converted to Islam.
What to today Jews - they are mostly descendants of Pagans (Berbers, Yemenite Arabs, Khazars, Slavs, etc) who converted to Judaism in the Muddle Ages.
Ergo: The "Jewish people" is an invention of Zionists, most of the real descendants of Judahites never left Palestine, though they changed their religion to Christianity and later to Islam.
