Why are other civilizations ignored in the Bible?

[Mr. Moncrieff]

If you believe that Jesus was born of a virgin as both Matthew and Luke assert, then it must be admitted that Jesus himself has no connection to either geneology. That makes them rather a moot point since the whole point of these things is to show Jesus' descendancy from David. It's a contradiction in itself to say that Jesus was "born of a virgin" and then try to prove a Davidic lineage through Joseph. Luke and Matthew disagree on that very genealogy though.

Matthew implies that Mary and Joseph were living in Bethlehem when Jesus was born and the magi visit them in a house. Luke says they lived in Nazareth and were only in Bethlehem to register for a census.

Matthew says that Jesus' family fled to Egypt after Jesus was born and then moved to Nazareth only after they had returned from Egypt and an angel told them to move to Galilee.

Luke says nothing about Herod's "slaughter of the innocents" or a flight to Egypt. He explicitly states that Jesus went to Jerusalem to be circumcised eight days after he was born and then immediately returned to Nazareth.

Luke also says nothing about the magi, or about a star or about the house where the magi visited Jesus in Bethlehem.

These are completely different stories and it seems that neither author has any awareness of the other.

We could go on - the last words of Jesus, the last supper discussions, the death of Judas, the details of the resurrection, the account of Jesus' baptism, the beginning of his ministry...
