Bible Started - Torah, Prophets, Ketuvim

A new script invented for the Jews, of which some 50% had been exiled into Babylon (west asia) and forgotten to read/write Paleo-Hebrew, therefore a new generation of old testament is written in Aramaic. The other 50% lived elsewhere as a result of the Diaspora, like North Africa, India/Russia, and Europe, and they developed their own traditions. (not rabbinic). There is no concept of a closed canon. But some fragmented societies seem to value more Prophets and more Ketuvim than other societies.
