You would be in the extreme minority on your view. Even most secular scholars who do not believe the NT holds any divine significance agree that most all the books of the NT were written in the 1st century.
I'm not saying they weren't written in the first century. I'm saying that the earliest copies of these texts don't themselves date to the first century.
And I don't think we have any of the originals.
I would love to be convinced otherwise.
