Don't act like you don't know what a demon is, you've probably come in contact with them several times.
Haven't you ever ejaculated in your sleep? Do you think that just happens randomly? Of course not, demons called succubi come and have sex with you when you are sleeping.
What do you think causes young, prepubescent girls to become pregnant? Do you think any full grown man would have sex with them? Nope, demons again.
They're all around you. You can't see them because you are blinded by atheist dogma, let the truth set you free.
