Whats the first Bible

Whats the first Bible The Greek Septuagint? If so where are the orginal manuscripts at? I read that the greeks learned in alexanderia egypt where all the works of the egyptians where housed at. Was it these works from the egyptians that they created biblical mythology since we dont know were the bible manuscripts at?

the greeks had the vast kemetic library. what vast library of the hebrews they have?
