You do provide large targets for the debunkers although of course you and a couple of others on the forum will never, ever accept reality.
"Cite the elements of a myth" This is easy, just use the online dictionary:
Myth --
noun a traditional story, especially one concerning the early history of a people or explaining some natural or social phenomenon, and typically involving supernatural beings or events.
I think you meant to ask: "how long it takes for a myth to be established as true?" The story of
John Frum tells us that it can take place within 10 - 15 years. For
Ned Ludd, it took about 30 years.
The concept of Jesus as a divine being born of a virgin human mother is not derived from a single predecessor myth but is rather a melding of multiple tales, religious beliefs and changes occurring within Judaism, at least partially driven by what was seen as the oppression of the Roman overlords in Palestinia.
In a post following this OP,
tosca 1 provided us with the usual apologetic nonsense and irrelevant material that seems to be the fall back position of the True Believers. Citing Thallus and Phlegon for an eclipse and earthquake taking place at the time of the crucifixion is probably not a good idea as there are no secular records of an earthquake nor zombies rising from their graves (Matthew 27:52) at that time. A couple hundred years later, Julius Africanus, while quoting Thallus, admitted an eclipse was impossible so the darkness must have been some miraculous action - in other words just more mythology for the rational.
The academic debate in regards to Jesus has now come down to those who say, "Yes, there was a guy named Yeshua, a relatively educated Jewish radical who wandered around Israel, preaching and prophesying as others had done before his time and others after his death continued." and the group that says "Totally mythological dude, created by that guy Paul, who was also a Jewish radical influenced by the society in which he lived and the changes taking place in his Jewish faith."
