That's just the oldest copy of what the Apostle John wrote. And don't forget Christ's ministry began ~28AD and the Apostles were fairly young men at the time.
I agree. Oral tradition is often at worst simplified. You'd spend a very long time memorizing it, and an even longer time repeating it to others. It's something for those with dedication to their religion, as ancient peoples often were.
