That’s not jumping to conclusions at all. We know precisely how video cameras work, because we created them. We know precisely how the human eye works, because we have studied it for centuries. We know that they both respond to electromagnetic radiation within a certain frequency range. And since we designed cameras to record stuff we can see, it responds to the same frequency range as the human eye.
Unless there is something we don’t know.
So no, there is no jumping to conclusions involved when someone says "If the ‘ghost’ appears on film, then it was visible to the human eye."
In certain cases that does not appear to be so.
Of course, there are some photographic artifacts that do not appear directly to the human eye – stuff like lens flare, double exposures, streaking, etc – because of the nature of how cameras work. Fortunately, we know how these things happen because humans designed the cameras in the first place.
And there are some photographic phenomena we nevertheless do not understand.
But more frames of video are taken every day than photos, therefore it stands to reason that there should be more ghost videos than photos. Yet that does not appear to be the case. Thus I must conclude that the vast majority – if not all – of ghost photographs are either photographic artifacts, or images that have an optical-illusion-like ability to be seen as something that they’re not for a single frame, but lose that attribute when seen in sequence with other images of the same thing from different angles or over time.
This is indeed an excellent argument. One would have to study a lot of videos frame by frame to see if anything shows up. It is a good idea for an experiment.
But evolution has mountains of testable evidence. Ghosts have a bunch of photographs and eyewitness accounts, but nothing more. For you to compare the two is laughable.
A gross simplification. Evolutionary theory is the playground of the creationists precisely because you can’t do lab experiments. I don’t know what you mean by “testable.” Ghosts have a lot more evidence than even photos and eyewitness accounts, which is quite substantial anyway.
And really, even if we look at all these pictures and eyewitness accounts and take them at face value, it says nothing at all about this phenomenon being ghosts.
Yeah, it says something, considering the actual content of the observations.
They could be psychic projections, aliens, extra-dimensional travelers, fairies, etc. To claim that they are ghosts is attempting to reach a conclusion that the (extremely lacking) evidence does not even indicate.
No, the content of the data allows for a very consistent and simple framework.
Instead, it’s a personal interpretation based on societal beliefs. If you had been raised in a society that had never believed in ghosts, but believed in aliens, then these pictures would no doubt be interpreted by you as being evidence of aliens.
Irrelevant, considering that the interpretational framework called “ghost” has been stable for thousands of years. Anyway, I could just as easily and glibly claim that, had you been raised in a fundamentalist Christian family, you would interpret the fossil record as being evidence for a great flood, and not for evolution.
And therein lies the problem. If evidence can be interpreted however you want based on what you want to believe rather than what the evidence shows, then it’s not evidence at all.
Then there is no evidence for evolution, since a creationist can interpret it however he wants?
Just because you don’t understand relativity well enough to argue it doesn’t mean that anything that you believe but don’t understand very well is true.
Certainly, this is true of every person on the planet.
There are experiments you can do to confirm relativity. There are no such experiments to confirm ghosts.
Sure there are: people go to reportedly haunted places and look for evidence of the haunting. And there they find it.
There is a vast body of knowledge and research on quantum mechanics, while ghosts have only personal accounts of strange happenings and some fuzzy pictures.
There are also pictures that are not fuzzy.
Just because you believe it to the same degree as relativity and quantum mechanics doesn’t mean it’s anywhere near as likely.
No joke. That wasn’t my argument.
And people have likewise believed that gods hurled lightning from the clouds and that the Earth was flat. Does the phrase Argumentum ad antiquitatem ring a bell?
The point was regarding the purported “unusualness” of ghosts. You are talking about something else.
