"There is only one story about the birth of Jesus"
In the Bible there are two. One is in the Gospel of Luke. It is well known "Christmas Story". Mary and Joseph go to Bethlehem, where there is no place to be received in the home, the child came into the world in a stable. On the other hand, Matthew says that Mary and Joseph would have lived with their son in Bethlehem. Magi from the East came led by a star and have honored the baby, but drawing the attention of King Herod - so the family had to flee to Egypt. Mark and John do not remember anything in their gospels, in connection with this event.
