We have no evidence of what was written. The vast majority of people were illiterate; the educated Jews had no particular reason to write anything about Jesus except to possibly mention him as a false messiah. The traditions were almost exclusively oral. We have Paul's letters and then the rest of the NT written perhaps starting 15-20 years after Jesus Ascended. The point is that most of the new Christians were convinced that Jesus would come again in their lifetimes and didn't bother with writings (those who could) until it became apparent that the second coming would be at some point far in the future.
That could be why we have so many “partial” manuscripts and why the originals disappeared after so much use and travel most any kind of scroll or papyrus would have long dissolved.
