A hole in a tree could be "suggestive evidence" of a giant(such as Sasquatch) sodomizing a tree. Or, it could be evidence that someone shot the tree with a cannon. Or it could be evidence that a laser was misfired and hit the tree.
That's a good analogy but only applies at a certain point, so it doesn't directly make sense. The evidence of "experiences" is suggestive at a certain point, but what happens to get you to that point is a head scratcher. For instance, if someone sees an apparition that communicates to them that they will be in a car accident next week... that is not something you have to wonder about what you saw. You saw something, but which spiritual platform can answer what you saw would be the suggestive part.
There are many spiritual experiences of this nature. Hearing a voice say you can heal someone and touching them and healing them, hearing a voice say don't go your usual route bc you'll get in trouble and you do when you don't heed the warning, asking questions and getting corresponding sounds to your questions from something that's not there, asking something that's not there to spin a necklace to the right and then to the left and it does it, etc. All of which above are spiritual experiences i've had. But lets not even count mine. I've heard a guy tell me that a random person in another state came up to him and told him to tell his mom not to go on a trip she had been planning. She said she was overwhelmed with a bad feeling so she had to say something; admitting it was weird for her too bc she's never felt this. The person was an atheist and didn't think anything of it. His mom went on a trip a week later that she had planned and was hit head on by a drunk driver. Etc. I can find a lot of these types of examples, experiences that are like mine and others.
Now, it suggestive in that we have no clue which spiritual platform can be responsible. We don't know if it's angels, demons, jins, gods, etc. That part isn't clear. But, the experiences people have are pretty clear in that they are pointing towards something of the spiritual nature. We can rule out, some times, natural explanations. And really, there is only a few natural explanations all of which is a cop out in my opinion. Bc all you can say is that the person is deluded or suffered from some kind of delusion. But that still doesn't answer the frequency in which they happen and to how many, most of the time, non-deluded people. I suffer from no mental illnesses' that would create delusion. Even if i did, it's curious how i only get episodes that are very specific and spiritual in nature.
So, you can say it's suggestive... but, it's not completely suggestive, only at a point it is. And what i'm saying is that it's enough to suspect spiritual platforms but not enough to believe. I think i am being as fair as i can be. Especially since i have personally had profound experiences, i still say suspect. I should be saying i 100% believe... but, you're right at that point in that the suggestive element to these experiences aren't enough for proof or iron clad belief.
