Or do you not believe that particular story?
If you check the Bible, ANY version, there is more than one view or version as to what was written on those tablets.
The final meaning is, pretty much, the same, but the 10 Commandments are translated and understood in many various ways.
This simply goes to show you the effect of history and translation and antiquity on what we are reasonably able to pass down, from generation to generation.
The Bible is intended to teach us how to live, NOT as a history book or a science book.
