A poor video, even by Jesus mythicist standards which tend to be pretty low. The kind of thing you'd expect a 13 year old atheist neophyte who thinks he's being edgy and subversive to come up with.
Gospel birth narratives are inconsistent and the Gospels aren't historically accurate (shock!) = Jesus must be a myth!
They are inconsistent because they are desperately scrambling to fit a real person who completely fails to meet the expectations of the prophesied messiah into the correct narrative. That Jesus is such a bad fit is one of the strongest reasons for his historical existence. Why wouldn't you just create an imaginary figure who actually matches expectations?
"Argument from silence" - this is only potentially legitimate if, based on the remaining sources, you could reasonably expect they should have written about him. This is not the case for one of countless poor preachers and prophets. Even then, he is written about by 'near contemporary' sources which is better than a whole load of other major historical figures, kings, etc.
Paul's letters to diverse preexisting religious communities within a few year of Jesus' crucifixion suggest a historical figure. Rapid spread of cults implies a central figure, cults that form around myth tend to develop long after the purported lifetime of the figure. AFAIK, a cult with a mythical central figure emerging concurrent with their lifetime would be unique in this regard.
"Historians didn't start writing about Christianity until after Paul started converting people" was my particular favourite though. Wow, people who write about significant issues didn't write about Christianity until it became significant?
