Ok now for some verifiable historical facts re new testiment. The earliest origional written records are Pauls letter to the Corithians 23AD. Marks Gospel 28AD. All of the gospel accounts written be the Luke, John and MaThew were all done by 75AD. pPlus on top of that you have a number of non Jewish historians, such as Josephus, who wrote extensively about Jesus. As to the collecting together of what was to be the new testiment was compteted by about 150AD. The Bible was not put together under Constintine or the 1st Pope. As to Jesus being uneducated- you clearly do not know how the Jewish cultures worked back then. A young jewish boy would learn of by heart the torah - the first 5 book of the old testiment as part of his education. It is recorded in the gospels that, as was the custom, a jewish boy would go to jerusalem and would go to the temple and question the scibes and priests about the scriptures and mentions that they were ammased at the wisdon of this young boy- that he had an exraordinary wisdom for his age. we have more origonal texts of the life, death, burial and reserection of Jesus then any other event of that time. For example we all believe in the historical account of Julius Caeser- but the earliest manuscipts to his lifetime are 1200 after he died. "He never wrote a word" - yet the witnesses of His life recorded in precise detail the events that we needed to know about. It is still the biggest selling book in human history by a huge margin. To have an accurate view of what He was all about, going to the writtings of Voltair, Nietzshie, lawrence Krass etc is obviously going to be futile. To know anything you need to go to the most origional accurate source.
