And what can be observed falls within the range of our basic senses.
That is not the case with indirect observation. One may observe the effects of a phenomenon on something observable, and reason a likely explanation. Observation of that thing would only confirm the hypothesis. If no effect from God can be observed, then it is a useless explanation. What indeed is it an explanation for? Religions do not say this at all, they say God has a very direct effect on our lives in a personal way.
What is the current, scientific analasys of ghosts and spirits?
Ghost and spirits are the hypothesis used to explain a variety of observations and feelings. So far, there is no evidence that such an explanation is more credible than naturalistic explanations, such as optical and auditory illusions and hallucinations.
Nor will there ever be any evidence, because it can only explain things from a naturalistic point of view.
There could be evidence of the supernatural, it just hasn't been found yet. You misunderstand science. So far the naturalistic explanations have been the predominant ones, but they are by no means the only possible ones.
Meaning that all knowledge is known only by scientific analasys, and anything else is irrational, and delusional. Great way to control people.
Not exactly. Some knowledge is experiential or inherited, guessed and intuited about. It could be useful, but if it cannot be confirmed scientifically, it is provisional, untrustworthy, folk wisdom.
My religion is the only correct religion, belief in any other religion is blasphemy.
Can you see the likeness?
No I don't. Because science uses rigorous methods to reach logical repeatable conclusions, as opposed to religions, which emphasize faith in something unconfirmed, something from a book, something unique to one individual and for which no investigation is admitted to be possible.
Science has to explain things in a naturalistic way, so there is no hope of science ever discovering the supernatural.
jan.
To be more exact, a naturalistic explanation but be ruled out before a supernatural one becomes plausable. Since naturalistic explanations are the only ones yet proven trustworthy, this is the present state of affairs. If the supernatural were discovered to be a more likely explanation for something, this state of affairs would change. If, for instance, an observable, repeatable effect were found, such as if a magic word pronounced by someone increased your chance of recovering from a surgical procedure, then a magical realm becomes much more likely, instead of the most unlikely thing imaginable.
It is only tradition and history that make naturalistic explanations the norm in science. It is not the rule in science. Science doesn't rule out the possibility of the supernatural competely, since it must consider everything. It's just that it is nothing more than an unlikely hypothesis at this point.
