Sorry I missed your post. Just answering your paraphrasing.
I have been told repeatedly from a scientific perspective, personal experience isn’t enough, there must be objective, observable proof which can be validated through replicable results and based on a falsifiable hypothesis.
I (and others) have said this kind of evidence is not applicable to the spiritual world. The scientific model is designed for,and largely good, at describing the physical world.
Therefore, I’m agreeing that anything physical should be assessed using the scientific model. If someone says only the physical/mundane world exists, I think we are all agreeing that proof should be by way of the scientific model.
Where one considers that there is a spiritual realm then there is a position that personal experience trumps scientific methodology (although some might contest that, this is my firmly held position),
I therefore, don’t see that there is any issue in applying these different types of proof depending on the question being asked.
