What philosophical evidence is there against believing in non-physical entities?

That is not evidence so much as it is thoughts led astray by fancy.

Right. Testimony and "records" are anecdotal. There hasn't been, as of yet, any actual evidence. It seems odd that as technology and data gathering exploded, the number of these accounts had dropped dramatically. It's almost as though people were just telling stories, and as our ability to test and call people out on these stories, they just decided to stop telling them.

Where do you get the data that shows the numbers are decreasing? Spirituality is an almost universal experience of human kind. There are more Christians today than there ever have been and reports of supernatural experiences are extremely common. I would estimate that probably 1 in 3 Christians have some elaborate testimony that includes a certain supernatural experience. That is over 650 million people.
