Supernatural beings can a) can manifest in the natural and/or supernatural worlds to a degree, and b) exercize some measure of control over one or both realms.
I'm 100% manifested in the natural world, and I have some degree of control over my immediate surroundings. (I can impart velocity to objects that I grasp. I can catalyze certain chemical reactions within my body at will. You know, that sort of thing.)
Am I supernatural?
Fallen angels are still around, disguised as UFO's and aliens and such, but thats another thread
You have it quite backwards - aliens and UFO's and such have always been around; until lately they've been disguised as fallen angels.
Since God is outside of physical reality as we know it, he is not subject to laws such as cause-and-effect
I'm not that impressed. Plenty of things
within our physical reality are not subject to "cause-and-effect", either.
