does demon really exist???

No and no.

Demons are very real. Satan does exist-I was married to him for ten years. :) There is a very good film titled "To Hell and Back"-it was put out by Jack Hayford Ministries some years ago. It is a real eye-opener. Also, a book titled "The Screwtape Letters" by C.S. Lewis will give you a good picture of demonic activity on Earth.

According to the bible. Satan or demon is real, but we can't see it physically. This creation by our God, is one of the things why people make sin. He want's all people be cast in the lake of fire...He want all people to commit sin...

i believe demons & satan are real if you dont believe wait till you pass onto the next life then you will find out but are you willing to gamble your life on that tiny doubt? youve been given life search for the truth and you will find it (:

it depends upon what you are looking for... when you look for physically evidence, i doubt that there is even a sufficient and reliable evidence that prove their existence not even the make-believe pictures of ghosts and spirits that people claim can give a satisfactory result i guess i am not convincing but then let me tell you my opinion i believe that they exist and they are not good because it is deliberately stated in the Bible furthermore it is already set in our hearts and mind that there is the existence of good and evil. Good represents God and Evil represents Satan, i believe God gave us this very simple thought to give us a warning of another ethereal being which is up to no good

Well I think they are real because people believe in them...Indeed if God exist so does Satan but he is not as powerful as God. People believe that the devil can hurt you but how if God will protect you from him? I just don't understand alot about different religions but Good & Evil, Ying & Yang, Light & Dark and Heaven & Hell does live regardless of what or how you believe

It's just my opinion based in my beliefs...yes, demons exist. Jesus has talked about them and has talked to them..they've talked to Jesus. I believe in Jesus, I believe what He says...therefore I believe they exist.

I think it is in a way that there are many evil entities, but not because they are separated from the creation, but because they were horrible human beings, like murderers, rapers, pedophilies and they are just that, that's all. They might be haunting for such a long time like 500 years or so that they become inrecognizable so when someone sees them they think it's the devil.
