>Making us believe that aliens or demons are different from us is the greatest psyop in history
Daemons are artifacts in a system.
The artifacts in the system that are demonic are sometimes controlled by people in spacecraft.
>It seems to me that demons and aliens are very old lost souls. That they are capable of invading bodies and taking control of the human body.
You can fight back against the demons and remove them. Supernatural, the show, isn't just a good guide, it actually looks like that when the demons leave a body.
Not all demons are old. Some are quite new. You, once you can see, you will see them walking around.
You'll never guess how many there are but the spirits that inhabit you mostly don't need to.
You can get a holy one when you try and ask.
