Previously, I responded to your post, but perhaps, you have me blocked and did not read my response. At any rate, as a Christian in this forum where you posed these questions, I will respond:
The first Bible?-- Firstly, the Bible is a compilation of many books written by many authors over the course of thousands of years so no one person wrote the first Bible. The First five books of the Bible was written by Moses. HIs writings were further kept by the Levite priesthood. The writings of Moses and other prophets were eventually developed into scriptures during the time of the empire period, I believe around the 500s BC.
The individuals that kept the ancient scripts were of the priesthood and over the course of time, the original scripts were translated by the Original people who had to learn other forms of script and languages.
