Why dont the jews fit the curses of Deuteronomy 28:15? (in particular 28:36,37,41,45,48,64,68)

I was always under the umtion that jewishness was just another religion. But then I heard a Rabbi say the Jews were actually the people of the bible. Thats when my head almost popped off ! First off , the tombs of Egytp and LOTS AND LOTS of other artifacts proves that those lands belonged to BLACK people. Second, its common knowlege that jews are from Europe and Russia (you cant have two origins). Third, they dont fit the cureses of DEUTERONOMY 28:15. Can someone explain whats going on?
