The miracle of it is NOT about how it comes to pass. The miracle of it is that to utter such a statement in a time when it was utterly impossible would seem totally sensless to the people who heard the prophetic statement.
But it isn't totally senseless. The problem with prophecy is that it is always sufficiently broad that you can take almost any event and fit it into the prophecy. I'm certain that apologists have been interpreting that prophecy and others as having been fulfilled. Some may have interpreted events into the framework the minute the prophecy was made.
It wasn't impossible to conceive at the time - words travel through the air when we speak them. If I didn't know why they did that, I might easily assume that the power of a god would be so great that his words might carry everywhere. No big deal.
If three centuries ago someone would tell you actural images/pictures would fly through space of things happening Tokyo and end up in millions of living rooms worldwide, you'd sware they were insane or illusional.
To the contrary, I would have called them a science-fiction writer. S-F writers have been predicting stuff for a hundred years before it happened - submarines, satellites, even computers - are they, then, prophets? Or just good guessers?
You clearly ignore the power of prophecy to be self-fulfilling. I could make any prophecy I pleased and if people thought it was important enough, they would find a way to either make it happen or interpret events into it. This has been going on since the Greeks.
