Fairies, dragons and magics might be real but not in this world I guess. Or if they're real in this world, I guess not all have experience them or see them. I guess there are unseen creatures /things/somethings we're aware and not aware of.
About divinities I guess they're real.
I believe that all the bad things, the horrific things are in the first place done by the demons or other evil spirits who influenced other people.
The question is:
How do we battle these evil forces?
If we can't see them or hear them, how do we know they exist? Because someone else said so? What if that person took LSD and then saw them, or consume peyote (magic mushroom) - does that mean that we have to use these drugs to see these creatures? Or, what if the person has a mental problem that makes them see these things? Does THAT mean they are real? Or, in either case, is it the result of a mental malfunction?
I have searched for supernatural creatures in both Indonesia and the US, going to places people said are haunted: houses, cemeteries and other places. One place, Lawang Sewu, in Purwokerto, Central Java, Indonesia, reportedly has a variety of supernatural creatures (over 35). I saw, heard and felt NOTHING. I have come to the conclusion that they do not exist. I possess several Indonesian keris, some of which are supposed to have been inhabited by supernatural creatures, but I've experienced nothing.
This phenomena, which is limited to being experienced by only certain people, is bound to be fallacious. This is not to say the people are lying, however, just that they are mistaken or hallucinating.
You believe in divinities? Which? I do not believe that the holy trinity is meant to be viewed as three distinct entities.
Keeping in mind our previous discussion about psychopathy, you now seem to be claiming that psychopathy is caused by malevolent creatures. I cannot agree with you LESS.
To answer your question: We do not. I do not believe they exist. Even if they do, it would require special abilities that we do not possess. I have seen TV shows purportedly showing human mystics fighting demons, but it was obvious that they were faking it - the attacks against them did not correspond with physics and were patently fake. If you believe in God, ask God for help.
I believe we have quite enough malevolent creatures on Earth that were created by humans - other humans, without imagining things that are not there. Sorry. Hell is on Earth, and Heaven, as we choose it. As you believe it to be, so it seems to become real.
