Certain Christians want to show that "everything" in that region portends the coming of Jesus of Nazareth.
They see the whole of the Jewish Scriptures (Old Testament) as a foretelling of Jesus' coming, not as a religious scripture in its own right.
They see artefacts from the entire region the same way. The don't see these ancient cultures in their own light. Everything has to relate to Jesus and the Bible. Their interpretation of the Bible.
