Do U believe on demons or ghosts?

I had always believed in Demons and not ghosts. Now that I have gotten older, I am not so sure about that, especially since my dad died 9 years ago.

As for aliens, ya. I dont think we are alone in the universe. Now, does it mean they are here now? Don't know.

Just want to say the belief in God and Angels is believing in Aliens. They are not from this world.
