We don't need so many brains, remember the thief on the Cross.
You do realize “how” and “approximately” when the New Testament was written?… It’s a “story” … best “guess” is that it was written at least a couple hundred years after all the major characters had passed.
While none of the writers were likely eye witnesses, the gospels were not written quite as long after the death and alleged resurrection as you say. The earliest was possibly 35 years after that, and the latest more like 70 years. Many of the letters of Paul appear to be genuine although some do date as much as 150 or 200 years later. There is a lot to question based on what we know. The language and dates of the gospels make it exceedingly unlikely that they were written by their eponymous apostles. If the naming was a marketing ploy it brings into question the validity of the content as well.
