Revelation was written 41 AD. Paul in 2 Corinthians 12, 55 AD said he knew someone 14 years earlier caught up to heaven that saw things that can't be written which is what happens to John in Revelation 10:4 ; an angel tells him don't write some things down. Paul doesn't say it was the author of Revelation he is talking about because he does not want to boast. Internally in Rev 11 the temple is still standing, and being destroyed which is describing the Romans doing it 70 AD, and Daniel 9 which ended 70 AD said vision, and prophecy would stop 70 AD, and Revelation contains vision, and prophecy. Dan 9 was saying inspired scripture would stop 70 AD. I reject external evidence if it conflicts with inspired scripture therefore I reject apocryphal acts of John (150 AD), and Irenaeus (180 AD) that say Revelation was written in the 90s AD under Domitian. They must of had corrupted oral traditions of when it was written passed on to them.
