So 20,000 people just all decide to write about some Egyptian story all within the same year. These people scattered around.
yes lol. why's that so hard to believe? after all, you do believe in a magic sky wizard.
if the people were so scattered, that only lends to my point. if events occur, it takes YEARS for that info to spread even a hundred miles in that time period. info was carried by word of mouth. it's illogical to think these events could have spread that fast. If, however, they had a main focal point from roughly 1000 years before hand, the information easily could have reached all of the encompassed.
