Sadly it seems you have a chip on your shoulder for this issue, further civil debate will unlikely not be possible.

Suffice to say no matter how badly you seem to want otherwise there are reputable scholars over the years and currently that believe that yes the authors of the letters and gospels are who they claim to be. There are others who disagree. It is a matter for debate and stating one side as indisputably factual is arrogant and wrong.
