- but there is one point you have not accounted for

- what actually happened may not be what was written

- what was written 5000 yrs ago may not be what you are reading now. lots of people may have created their own versions or modified the original in ways you did not foresee

- the author who originally wrote the books may also have exaggerated for storytelling effect

- the probability of all of the above mathematically speaking is non zero
