The Bible, the New Testament, and the Quran all acknowledge that Jews were chosen by God to receive the Ten Commandments and lead to the promised land. Yes, this may all be fabricated ancient stories, myths, fiction, but all three religions have bought it.
The reality is that Jews did return to build the first independent nation in the geographical area of Palestine since the Romans sacked Jerusalem 2000 years ago. That is not fabricated, not myth, not fiction.
And to you last point, religious Jews, Christians, and Muslims all believe in their own BS. Hamas Charter: “The land of Palestine is an Islamic Waqf [Holy Possession] consecrated for future Moslem generations until Judgment Day. No one can renounce it or any part, or abandon it or any part of it.” (Article 11)
