Jesus had no parents

[Ranjr]

Paul makes no mention of Jesus life in terms of his sayings, miracles, place of birth, or events of the gospels.  Apologists respond that Paul was giving spiritual advice through his letters and expected his audience to already know the tales of Mark.  Sceptics ask what better advise than Jesus' own teachings?  And add that gentiles in Paul's audience would be unlikely to know the story and teachings of Jesus, especially since Mark was written after the letters of Paul.
