You just proved my point if you read what you just posted,125-150 AD, thats is quite a while to write something after some one has been dead for 150 years.
Back in 150AD it would take months to travel from one part of the empire to another. It would also take months to make just one copy of a book. By already have copies all over the empire it means we can push back the date by at least 50 years. Further the dead sea scrolls push the OT canon back to the 1st century AD
No these are the earliest handwritten copies that have survived throughout the centuries. There is a lot of evidence involved in dating the New Testament texts but even the most skeptical scholars grant that a number of the books were written in the first century within a couple of decades after Jesus’ death, claiming that others were not written until the second. Their evidence is weak, in my opinion, and the early statements of the church fathers place all of the New Testament writings in the first century.
You on the other hand were saying that Constantine just made them up and started Christianity and the church in the fourth century. If the copies were already there as well as numerous references to them and Christian activity in general as of the beginning of the second century, you are refuted.
