Does not matter how far back you go.
Historically there really is no valid "Israel".
When the Hebrew tribes invaded the Land of Canaan around 1000 BC, they called the area around Jerusalem Israel, but only for about 150 years, and it was invalid because they were evil invaders who massacred the native Canaanites, for no valid reason.
And mass genocide makes a country invalid, not valid.
The Romans created a fake Israel again around 100 BC. but it only lasted until around 60 AD and the Jewish revolt was suppressed by the Romans.
There has never been an Israel really until the UN made it up on 1948.
And that was a huge mistake because the UN did nothing to defend the rights of the Arabs who owned land in the newly created Israel, and did nothing when Israel violated the 1948 partition by invading Jerusalem and the West Bank.
There really is no excuse for that obvious theft of Palestine by the Zionists.
