Enoch, the oldest manuscript said to be.

Enoch lived 365 years, never died but was taken. His life is recorded to be in and around 3200 BC. His manuscript more than likely kept by his son Methuselah, could have been transferred to Noah who survived the Flood. Noah was the grand-son of Methuselah. Methuselah however, died during the Flood.
