Yeah. It ended with the invention of writing, printing, photography, and other methods by which truth can be reliably transferred between generations. --dano

not exactly...writing preceded the close of the miraculous era by more than a couple of millennia (actually several but the earlier evidence was probably lost in the flood...although some of adam's writings may have survived and been passed down to moses, but we probably won't be able to be sure about that until...that day)

printing ~1350yrs after the close of the that era

photography ~1700+yrs afterward

so no...you missed on all counts

none of those things was even mildly associated with the passing of that era...it was determined by the completion of the book at the end of the first century

the good news is...we all gonna know the truth one day coming
