The Greeks treated their mythology as a part of their history, but we know what parts are history and what parts are mythology because of the supernatural claims.

Through many cultures historians have a problem being able to determine the difference between history and myth, because of supernatural claims. This is common in studying Japanese history books and Serbian history writings. I do not make the same mistake of favouring Christianity as you do.

Again, there are only 4 fundamental forces, not trillions of causes, so we can't "go with the evidence", because there is none. Also, time breaks down at the quantum level, before you make any arguments about infinite regress you need to explain how quantum time works.

The 4 fundamental forces explain how people wrote fictional books in the past, therefore the disciples actions are explained.
