Hi Abigail, (((( Smiles ))))

If they are seeing any of these supernatural beings they are not human that's for sure. The only thing the Bible mentions in the air and around us are fallen Angels demonic force's and they could manifest and poise as aliens if they wanted too. And try to spread the gospel of E.T around and that's what is being seen by those who see them.
The Bible talks about that the end times will be times of great delusion and deception so why not this too?
Maybe some are being visited by what they call Aliens so they believe in the Supernatural as being true but can't except they are supernatural fallen creatures created by a powerful God. Who could also be considered a Supernatural being too.
Except A Powerful Creative God Above All His Creation the first cause. They do not want to except that..
That's for sure.
