Everything else about the bible not being the divine flawless word of God we can all agree is true, the bible has a lot of problems, I think even Paul was a false prophet.
To be fair, there is proof of an historical Jesus but does not say much about him or anything special about him, there was thousands of old texts from the NT in circulation in those days a lot more than any other books, early orthodoxy decided what went in the bible and they had to be in harmony with the four gospels (you can see why barnabas and thomas was never included, rev and hebrews shouldnt be in the Nt), all apostles put their life on the line this shows their believe in faith. When Jesus passed to heaven, other documents mentioned darkening of the that day in other countries which is in harmony with what the bible says (astronomy can not prove that this was an eclipse), the oldest book (page of the book) found which dates 70AEC was JOHN.
