I am not talking about non-material experiences. These may exist but I don’t know. I am talking about experiences in which matter (bodies, the sun, etc.) is claimed to have been changed in ways that could not occur naturally.
But you are asking for “material” proof for an immaterial reality, which you have not even defined, and seem to deny exists.
My standard of proof is the same we apply to medicine, bridge-building and car manufacture.
This is my point. Which of these areas of inquiry explore that which is intangible?
We observe how matter behaves and draw conclusions.
Those of us that know that all reality is not contained in matter that behaves also observe and draw conclusions.
‘Faith’ in rejecting these standards of proof is very common and goes beyond religion into things like belief in acupuncture, homeopathy etc, all of which can be shown to not work better than placebo but this fact does not stop many people spending money on them.
You have confirmed that your cognitive bias is even more severe than you did at the outset!
Acupuncture, homeopathy, and other interventions have been in use and effectively treating health problems for millenia. Your mind has been significantly narrowed by Western materialism.
The fact that placebos work (which also has been scientifically documented), has to do with those same non-material elements of human persons that you are denying exist, such as expectations, attitudes, values, and beliefs. None of these are materially measurable, but significantly influence human behavior.
The same standard we would apply to any scientific claim of an observation.
Your “science” is much too narrow to apply to any human experiences beyond the physical. If you believe that humanity is limited to only physical things that can be observed and measured, then you cannot rationally explore any human experiences that cannot be determined while a person is in a coma.
In fact, the vast majority of human experience lies beyond the narrow confines of the parameters you have selected.
