What Is the Earliest Writing of the New Testament?

i love the bible stories that have no corroboration outside. I think my favorite example is at the crucifixion of christ, when the dead saints rise up out of their graves and they rade through the streets of jerusalem. No contemporary historian thought that was noteworthy. Enough to chronicle redit thes the zombe apocalypse and n ansetha. Most christians do not know or care that paul's writings are the earliest of the new testament.
