This is a good point, there was a discussion somewhere about this, something akin to a Ted Talk. Basically the majority of old structures will never give way to something new, the core religions of the world will brook no opposition or interference. If Jebus was to arrive tomorrow he would definitely have to lean heavily on the magic miracles, and even if he raised someone from the dead again, or stopped bullets like Neo, they would still say he is not our the guy. Governments also don't like miracles, it makes the nervous, it gives people ideas and makes them uppity.
I'm not stating here that one thing is real and another is not, how the heck would I know. All I see as I've gotten older is that many have made/convinced themselves that we are the pinnacle of creation, the darling favorite of the divine, and we know how the cosmos/existence works. We're such imaginative rascals.
