Well, Jules Verne predicted submarines, airships, trips to the moon, all of which has come true, but we don’t call them “prophesies”, do we? Science Fiction writers have predicted many things, political situations, aliens, future wars and weapons. Some of them became true, some of them did not and some of them might still become true in some fashion or another. These are guesses, sometimes based on current knowledge, on speculative science or totally on fantasy. They are not prophesies. Predictions of calamities, natural disasters are also easily “fulfilled” since these are part of the natural world we live in. Biblical prophecies fall in the same category or are written after the fact to make it look some prophesies were fulfilled. To have actually predicted the future, as Jules Verne did for example, is not divinely inspired.
Nostradamus’ predictions of wars. disasters and political happenings, received torturous interpretations to fit some factual happenings since and therefor other ones are not to be taken serious as future predictions. Some guesses might be twisted to “prove” their accuracy but they are not divine revelation of a Deity. The Seers and Psychics of this world rely on the fact that when they accidentally guess something correctly, it gets remembered and advertised, and that all the failures of these “experts” are forgotten or ignored by their fans.
The conclusion is that prophesies are not divinely inspired. But are speculations on the future.
