Ghosts don't exist, however demons do.
Aliens, ghosts, etc. are simply demons appearing to people whom are not saved.
If you were saved, would you really want to play with the devil? That's what a ouiji board is, it's a tool for asking the spirits(demons) questions.
Why do you think when you asked if there was a God, it said scum. And it's name was dangeous? We are all in a spiritual warfare. War is going on all around us, even if we can't see it.
The Bible predicted the re-construction of Babylon, look up in an atlas where babylon once stood, and you'll find the area the united states is currently trying to rebuild and turn into a democracy.
If you acknowledge the existance of demons, which no one here can deny, then you acknowlege the existance of angels, because that's what a demon is, an angel forever condemed because they chose to follow satan. And if you realize this, you also realize God is real.
Quesh is a demon whom you interacted with, and he wasn't lying when he said you weren't safe.
He may of been trying to scare you, because you should be scared, but he also did something without realizing it, after all, he's not perfect. He told you that you need to be saved, if you are not, you're not safe, for if you die un-saved, you'll experience the same torture that this Quesh will.
However there are 2 times more angels than demons, so if you become saved (genuinely), you will be safe from the demons, not to mention that demons can't mess with you unless they ask God permission first, if you're saved of course.
EDIT: this is a very real and very serious subject.
