You may or may not be surprised to find out that you know nothing about the origin of Palestinians. When Joshua led the 12 tribes of the Israelites across the river Jordan into Canaan, also known at that time as Palestine, the land was inhabited by (among others) semite tribes, Hittites, Amorites and Jebusites. The Jebusites had built Jerusalem, and they inhabited it for 100 years after the Israelites entered Canaan.They weren't called Arabs then, and the Israelites weren't called Jews. Those names weren't known yet. There are many notable historians and scholars who have determined that the Jebusites are the forebears of the Palestinians. According to the New York University School of Medicine, and the National Academy of Sciences, Middle East Jewish men and Palestinian, Lebanese and Syrian men have the same genetic signature, different from any other non-Jews in the world. Some of those same tribes, and the Canaanites also occupied Judea and Samaria.
