all I had to do is read the first sentence and I knew exactly where this is going and the following would just be a repeat of things I've read a million times before
It seems theres no middle ground to be had because you think that middle ground is dominated by science, which makes it far from the middle... You seriously preach this like a religion and you wonder (and assume) why people dont accept your point of view...
I can pick up my bong, I can smoke it, I can show it to other people, they can smoke it.
In the absolute broadest sense, you can use science to confirm it exists, by proposing a hyposthesis;
"My bong exists"
Then you can perform an experiment and smoke from it, this verifies your results. After verifying it for yourself, it's time to replicate the experiment; so give the bong to your friend and let him/her smoke it. If they can see it, grasp it, and smoke from it; you have replicated your results and have successfully verified that the bong exists.
For 'things that exist' an experiment like this is very doable. Depending on what objects are used, you may need to use different equipment to measure with. You can't very well grasp X-rays, but we certainly do have things to measure X-rays with, that's to say X-rays have a definite measurable interaction with reality.
Until we can see a clear demonstration of the more controversial concepts you and many other people bring to the table, there is ZERO reason to believe they exist. Even if we couldn't measure the reactions, we should at least be able to see some sort of interaction with reality.
That's to say; we might not know how telekinesis works, but we should be able to see it demonstrated. We may not know how astral plane walking works, but people should be able to demonstrate NEW INFORMATION, that is unavailable to the outside world, but they gained while on the astral plane. We might not know how the 6th sense works, but it should be demonstrable under laboratory conditions.
NONE of these, or any other SUPERNATURAL (it is supernatural until it's proven natural) concepts have ever been demonstrated.
