No, the Ethiopian Bible is not the oldest Bible. This is a common online claim, mostly because people compare the Ethiopian Bible (which was adapted by Ethiopia during 1400s) with the King James Bible (which was complied during the 1600s). Neither translation is the earliest scripture.
The Ethiopian Bible
For the Ethiopian Bible (the canon of the Ethiopian Orthodox Tewahedo Church, written in Ge'ez):The translation of biblical texts into Ge'ez began in the 4th–6th centuries CE, soon after Christianity became the state religion in the Kingdom of Aksum (Ethiopia) in the 4th century.
The oldest surviving Ethiopian biblical manuscripts are the Garima Gospels (illuminated manuscripts of the four Gospels), radiocarbon dated to roughly 330–650 CE (with some samples as early as 390–570 CE). These are among the world's oldest illustrated Christian manuscripts and the earliest in Ge'ez.
However, a full Ethiopian Bible (with its broader canon of 81–88 books, including texts like Enoch and Jubilees not in most other Christian canons) as a complete, compiled collection appears in later manuscripts.
The oldest version
The oldest surviving nearly complete or complete Bibles (as full codices containing both Old and New Testaments in one set of manuscripts) date to the 4th century AD.
Codex Vaticanus (c. 300–325 AD or slightly later): One of the earliest and most complete Greek Bibles (Septuagint Old Testament + New Testament), housed in the Vatican Library. It is missing some parts but is among the oldest.
Codex Sinaiticus (c. 330–360 AD): Contains the oldest complete New Testament and large portions of the Old Testament in Greek. Discovered at St. Catherine's Monastery, it is widely regarded as one of the most important early biblical manuscripts.
