I like the super spectrum theory where ufos (which aren’t aliens), cryptids, and other weird things like gnomes and fairies are present but they are on a different wavelength or almost like parallel dimension. Then I would classify these beings into two groups, natural or supernatural. Natural would be God created things like Bigfoot or the dogman. Supernatural would be wendigos, ghosts, ufos, etc. These beings I believe are demons.
In the case of wendigo, skinwalkers, and other stuff like that, these are pagans who actually do have supernatural powers derived from deals with demons. There are many medicine men, witch doctors, and other pagan healers in the world. While I do think that most are just more in touch with the natural world and our own bodies, there are some who wether knowingly or unknowingly invite demons into their life.
The reason why I believe ufos aren’t aliens and are in fact demonic is simple. Aliens make you doubt and make you feel small in the universe. It’s as simple as that. Aliens aren’t real and don’t come from other planets, they are simply another way for the devil to tempt us and make us stray from God.
I will save my hate and disgust of the Smithsonian for another day.
