Can Revelation be proven by “real world facts”? I think not. It is not one of the four great books, whose history is indisputable.
Only God, Himself, knows the end from the beginning — which happens to be the *verification* for Scripture. And since all things for the future haven’t happened yet, you’ll have to wait for the verification on certain parts of Scripture.
You’ll note that I said, previously, “In all areas where the facts have been able to be checked the Bible is right.”
Some facts are future, and will await their *actual occurrence* for verification (in the same way that Jesus’ coming was “future” at the time before He arrived on earth the first time). These events in Revelation are also “future” (for us..., just as events were future for those people back in history at the time of His first coming). And these are events for Jesus Christ’s second coming.
For those parts which have already happened, we have the proof.
So, you’ll get your proof, when God’s pronouncements about the “future” become the “present”... :-)

And, once again, you’ve got the same “mentality” of others (too) — which indicates that “mankind” gets to pick and choose what is okay for God to say and what He shouldn’t say. Sorry, all of Scripture is God’s word, whatever books He had His hand in being written.
