Illiterate men.

Q1) Is this credible within the pages of the NT? Jesus is meant to come from the lowest of the low. How does he gain the resources to get an education?

First to answer the original question why was nothing written down. I asked who to say nothing was? It was a massive undertaking and extremely expensive to not only get writing materials but to store said writings in such away as to be preserved. One had to know people, and unless you were a scribe or Pharisee yourself it would be most likely your efforts would have been lost. That is why in that culture in that time the oral tradition of verbally passing down accounts were held in such high regard. Remember there is nearly a 70 year gap between the events that had taken place until the newly form church had the resources to record and story the written works of the remaining apostles.

The answer to this question:
There is a story of Christ as a young child being lost by His parents for 3 days, and was found teaching the rabbis in the synagogue. Apparently He did not have a need for a formal education.

Q2) The implication is that the author mentions that John wrote down everything else except this ending, because the author refers to himself as someone apart from John. What can we say historically about the Gospel of John and how it came to be? Is the anonymous author giving credit to John for his own work, by making it seem like he only added the last portion that says John wrote everything?

There are 3 other works accredited to John aside from the gospel account. writing style and subject matter coupled with how he identifies himself all point to a singular authorship. That said it was not uncommon for men like John to use a Scribe to record what he himself could not.
