do you believe in Angels and Demons walking the Earth?

Since we humans are supposed to have free will I would guess the only purpose angels have here on Earth (if there are any on Earth) would be to protect us from the demons and just allow the world to evolve by itself even letting us destroy ourselves. So no they most likely don't unless they are ordered to by god... or maybe to save someone religious who's attacked by a demon. Since demons are evil spirit then I would also guess that they do walk the Earth... The world is riddled with dirty unclean pure evil spirits even if their existence is a confusing mystery to us. Natural disasters: caused by demons, angels, or just natural?

yes but not demons as bad or angels as good demons are here to help us when we ask plus alot of demons are born from our negativety their not fallen angels

for their presence in the world I believe they were here but for showing as a human form I'm not too believe because even they live around us they actually have their own world which is different with our world. They could be appearing by human helps likes mistic things likes intermediary...

No! No material formation but thoughts is what that counts. Human formation came from human mind and form a figure. Angel are messangers of God, they said to have wings because they are fast while satan and the devils aka the evils or the lie and liers thought.

Yes, angels and demons are with us but we cannot see them visibly. The Holy Bible spoke for them. Our world is in confusion because of the war between good and evil. Satan is the root of confusion in our world which we could not deny because of the turmoils, disasters, religions, politics, etc. We can eradicate Satan by surrendering our heart and mind to God.
