when he wrote revelation has been a debate since the Bible existed there are two main schools of thought and niether side has proof it’s just a matter of what a person believes and the information they have about early ad history
That's funny. In other words," I don't care if the truth hits me between the eyes, I ain't changing my mind!"

Irenaeus
Irenaeus (A.D. 180), a student of Polycarp (who was a disciple of the apostle John), wrote that the apocalyptic vision “was seen not very long ago, almost in our own generation, at the close of the reign of Domitian” (Against Heresies 30). The testimony of Irenaeus, not far removed from the apostolic age, is first rate. He places the book near the end of Domitian’s reign, and that ruler died in A.D. 96. Irenaeus seems to be unaware of any other view for the date of the book of Revelation.

And to top it off, Polycarp and Irenaeus and all of their contemporaries had every chance to say, " John was RIGHT! The whole book of revelation was fulfilled just a few short years ago, the eye witnesses and history scholars have written many,many books on this once in a life time great showing from our God !!!! We have many more things to write to prove to the world that it truly did happen!"
It would be a doctrine of the Church today if It did happen. It would be a truth taught on the scale of the Gospel.
