Yes!!! Read Genesis Chapter 6. It's Biblical! These are Fallen Angels and Demons we are dealing with. This is a fight of Good versus Evil. Read Ephesians Chapter 6. It says we are not fighting against flesh and blood, but principalities and powers and evil spirits in high places! Demons are all around! (As are God's good and holy angels too.) They've been here since the beginning. They've never left. Call upon the name of Jesus to be saved TODAY! John 3:16.
