the purim revelation

The question you need to answer is:
What is a natural explanation of how a text written over 2000 years ago has an anomaly in it, in exactly the relevant part of the text, which points to the exact year, that exactly the same thing happened, to exactly the same amount of people, for exactly the same crime,                            the only other time in recorded human history?
(I'd suggest watching at 1.25 speed, as long as you can still register all the infomation)
