  Western Civilization has many, many sources. Christianity played a major role, and it fused Jewish monotheism and Jewish ethical values with Greco-Roman culture and philosophy.
  Persia/Babylonia, Egypt, and other ancient cultures also played a role.
  One small example, there's a huge debate as to the origins of the Western-languages alphabet, which can be traced back to the Romans and then to the Greeks. A lot of scholars then trace it back further to the Phoenicians, but some scholars argue Hebrew is just as ancient as Phoenician.
  The first four letters of the Greek alphabet are Alpha, Beta, Gamma, Delta.
  The first four letters of the Hebrew alphabet are Aleph, Bet, Gimmel, Daled.
