I’m not going to try to convince you to believe anything. I believe that anything other than what the Apostles wrote becomes suspect. Certainly given the Apostles never once mention Mary after the Ascension of Christ is very telling. The entire Mariology myth is built on speculation and hearsay and not on scripture. If that is the religion you want you have made your choice and will have to answer for that.
I think the firm position is that history stopped after the Book Of Acts.
I.e., there was no final result of the trial of Paul, the Apostles froze in place, the Church went dormant, etc.
Until somewhere around the 16th Century when history started up again...
