I didn't say that. The things written in Revelation about the Anti-Christ are referring to contemporary events occurring during the authors lifetime. The author is writing a book of encouragement for those churches living through those events. This included incorporating Gnostic imagery, elements of mystery religions and adaptions from the book of Daniel there's other apocalyptic texts from the same time with similar imagery, verses and themes that aren't included in the bible but non-the less echo similar sentiments. I don't doubt the author thought that the prophetic events about the 'end of the world' were going to happen - just like every apocalyptic cult throughout time has believed their own eschatology and have been utterly convinced of it. I also don't doubt they probably had some kind of vision - but that's not really remarkable considering human kinds affinity for visionary states of consciousness, all takes it a few of the right plants and you're communing with God/Gods, the universe, aliens etc...Obviously they were mistaken in thinking their vision of the future was coming to pass and it's a huge fallacy to read the book now in 2018 and assume that you're the intended recipient of that vision and that it's still on the table. The belief that Revelation holds some-kind of future prophecy is a relatively new theological development in the history of Christianity and really as this thread is titled a conspiracy theory...
There are 4 seperate Biblical views of eschatology. Yours is only oe of the four. I personally find it ridiculous since the antiChrist is foretold to come in the end times and not past tense. In prophecy many times there is a type of fulfillment coming before the real fulfillment.
