Contrary to the contentions of Wellhausen, who maintained, against archaeological evidence already available in his day, that writing did not appear among the Hebrews until the early monarchy; they had the means of producing written records at their disposal from very early times.<quoted text>
one has to wonder what "written" language was used, seeing that "Hebrew writing wasn't even in existence until between 1200-1100 BCE, and so far, no writing has ever reached much past 4000 years in our present knowledge of civilization.
Until such time as that knowledge is refuted, I have to categorize that statement as an "argument from ignorance", or an outright lie.
Moses who is credited with writing the Torah (Five books of Moses; Genesis, Exodus, Leviticus, Numbers and Deuteronomy) was educated in the house of Pharaoh, he would have been literate not only in Egyptian but the surrounding cultures in his day.
In the book of Job, dated to the Patriarchal period (2100-1800 B.C.) before the time of Moses, Job refers to writing and the material on which one writes. Writing with an Iron pen upon stone and lead is clearly described; lead a soft material could be inscribed with an Iron stylus. Soft Clay was also a material used to write upon, preserving the words of the writer.
"Oh, that my words were written! Oh, that they were inscribed in a book! That they were engraved on a rock With an iron pen and lead, forever! Job 19:23-24
