The Bible is not a scientific document, it would be over the heads of its ancient audience, also ancient Hebrew writing is more poetic and structured than it is factual.

Form was most important to ancient writers and extensive poetic license with the details was taken to accomplish a well structured piece.

The ancient audience could not take it home and repeatedly read it for themselves. The poetic nature and repetitive elements aided memory and recall after hearing the passages read in gatherings.

One simply needs to memories the first part of the structure and then that acts as the prompt for the remainder of the structure.
