What's more likely, aliens or ghosts?
Aliens. If God created the whole universjust for us, that's an awful waste of space.
So if Good created the universe. Wouldn't that also mean souls are a thing and that ghosts would also be likely?
I believe in ghosts because I believe in everlasting life. But you asked about probability.
Demons, whites are evidence
Demons are different from ghosts.
Aliens
Why do you think aliens?
