Considering that the book of Enoch is not considered part of inspired Scripture -- you might want to stick to inspired Scripture. Scripture says that 1/3 of the angels rebelled and were kicked out of heaven. Lucifer became satan and the rebelling angels became demons. They are all still active down here on earth. It's called the invisible spirit world.
As an example my dear friend, you seem to be saying fallen angels are demons...That's NOT in the Bible...That's extra-biblical Churchianity.
