The words of the concept of God are just man’s words, and the stories of performing miracles are all fantasy and fiction, like that of every religion. There is no question about factual Jewish history in the area because you would no have Christianity or Islam which was born from the Hebrew conception of God, Ten Commandment, former Prophets, dietary laws, the Holy City of Jerusalem, which is important to Jews first, then Christians, and then Muslims.
Israel is Jewish because Jews for this piece of real estate and built a viable nation at the forefront of science and technology. They are the first independent nation on that piece of real estate since the Romans sacked Jerusalem 2000 years ago.
My question to you is—- Muslims pray to God five times a day for favor and guidance, is that why the banner of Islamic flies over 99.9% of the Middle East and North Africa land mass? In other words, did God give that land to them or was it taken through warfare and dominance? What happened to all the people in those geographical locations that rejected Islam, sharia, and refused to submit?
