If "Harry Potter" does not actually exist "in Hogwarts", then how do humans on Earth know Harry's name? How did humans hear of the "Hogwarts School of Wizardry and Witchcraft" if they didn't hear from it ?
How many
miracles has J.K. Rowling worked? How many times has J.K. Rowling attributed her "creative inspiration" to
Divine Voices & Visions ? And for how many
thousands of years running have others been adding to that body of writings, in an (allegedly) supra-naturally complex, mathematically structured, and sophisticatedly self-referential way?
And, of course, how many times has anything in those pages actually been born out in (archaeologically attestable) physical reality, for all human eyes to plainly see?
Abrahamic Scripture is not just some single fire-side story. It is a (supposed) historical record of "God in heaven's" (alleged) miraculous wonder-working upon this planet over the past ~
8000 years.
What about the (claimed) "Plagues"
vs. Ramesses' Egypt that do coincide archaeologically, not only with the end of Ramesses the Great's reign, the onset of identifiably Israelite occupation of Canaan, as well as some sort of retaliatory raid against "ISRL" by Ramesses' successor Merneptah attested on an Egyptian stele... but also the "Bronze Age Collapse" which wiped out civilizations around the region and plunged the eastern Mediterranean into centuries of Dark Ages?
Something major happened. Troy fell. The Greeks collapsed. The Hittites failed. The Egyptian empire crumbled. Other than perhaps the Philistines (who themselves appear to have fled to Canaan from somewhere else), the only humans around to actually
benefit was a group of refugees hiding out in the Arabian wilderness, claiming to receive Divine Guidance
via Divine Voices & Visions from "God in heaven".
I guess if you actively desire to reject such claims, you could claim it "just happened" to be a one-in-a-zillion string of fortuitous random coincidences which "just happened" to turn a bunch of Egyptian slaves into the regional power of Israel...
I guess what I'm trying to say, though, is that I find no reason
per se to reject the claims. If there actually factually was (and is) a "God in heaven" capable of communicating meaningful, intelligible audio-visual messages (Divine Voices & Visions) to humans on Earth, then such an "uplink" to Divine Guidance would be able to steer a group of humans through plagues, locust swarms, earthquakes, volcanic eruptions, tsunamis and/or whatever else happened to power & prominence in the (supposedly) "Promised" land.
I see no reason to dismiss such a scenario out of human hand. Are humans somehow doing anything to somehow "stop" or "prevent" or "shield against" such Divine Voices & Visions being communicated successfully to humans on Earth?
Why are you so incredulous? What might you know about "heaven" that the rest of us don't? Humans don't really know exactly how Quasars, Blazars, or Gamma ray Bursts work, but we think we detect them regularly all the same. It's a puzzle, hopefully humans will figure it out some day. Meanwhile, other humans think they perceive a "Divine Presence" from "God in heaven", communicating to their minds audio-visual Voices & Visions. Why is that impossible? And if it is possible, what is anybody around here doing about it, much less to (say) somehow stop it. I don't understand your dubiousness. Nothing I notice in any way "violates the fundamental fabric of space-time" or anything. "God in heaven" can affect our "pale blue dot"... insofar as we now know our "pale blue dot of a planet" isn't really much of a big Cosmic deal, then such a claim is not really much of one either.
