I watched the movie The Fourth Kind because I was curious of how it connected alien abduction to demonic possession. It shocked me to be quite honest. Knowing what I know about both worlds, there is no denying that they are one and the same. Especially after discovering more evidence of that speculation. I have yet to have any concrete evidence to support the things I am learning. So far, I believe I'm on the right track to making reliable conclusions. I was previously wondering what unclean spirits were from their mention in the book of Mark. I speculate that they are the Nephilim spirits who are hybrid offspring of the fallen angels and ancient women. They are unclean because they were never supposed to exist. I also think that the purpose of the flood was to cleanse the earth of such species. Water was needed, which is why water baptism is required now as part of salvation. It could also be to make sure that the human being that was getting baptized was, in fact, a human and not a Nephilim since they seem to be traumatized from the flood.
For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened by the Spirit: By which also he went and preached unto the spirits in prison; Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water. The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ: - 1 Peter 3:18-21
And when he was come to the other side into the country of the Gergesenes, there met him two possessed with devils, coming out of the tombs, exceeding fierce, so that no man might pass by that way. And, behold, they cried out, saying, What have we to do with thee, Jesus, thou Son of God? art thou come hither to torment us before the time? And there was a good way off from them an herd of many swine feeding. So the devils besought him, saying, If thou cast us out, suffer us to go away into the herd of swine. And he said unto them, Go. And when they were come out, they went into the herd of swine: and, behold, the whole herd of swine ran violently down a steep place into the sea, and perished in the waters. - Mark 8:28-32
Fear drove the unclean spirits. They died in the waters because that's what their destiny was supposed to be from the beginning, to perish in the waters - the flood. They were able to possess the swine because that's all they can do is possess things, animals, and people. They need a host because they don't have the ability to manifest themselves physically since they were part man and part angel in the first place. Fallen angels, on the other hand, can display in all kinds of forms, visually or not. Such as shadows, ghosts, reptilians, shapeshifters, etc. The unclean spirit that was talking within these scriptures mentioned being tormented by Jesus before the time. Insinuating that there was a plan involved, perhaps the plan for their spirits to be cast into hell when judgment arrives. They probably saw Jesus and thought it was already the second coming, so they got even more afraid, thinking Jesus was there to judge the world early. They knew it wasn't time yet. I'm just making assumptions, though, as logically as I can to make sense of these things. Again, no real conclusions.
