The point is that when the writers of the gospels were creating the story of Jesus the writers, being Greek scholars, drew heavily on the mythology of their own demi-gods and heroes like the following:
Oedipus (21 or 22 points),
Theseus (20 points),
Romulus (18 points),
Heracles (17 points),
Perseus (18 points),
Jason (15 points),
Bellerophon (16 points),
Pelops (13 points),
Dionysos (19 points),
Apollo (11 points),
Zeus (15 points)
It's a question which came first, Jesus or the Greek gods. Of course, the Greek gods. Naturally the writers, not having any written evidence of Jesus' life, would turn to their own mythology to create a "life" for Jesus.
