IMO extraterrestrials are not what you think they are, through personal experience I've come to the conclusion they are either fallen angels or demons. The whole concept is just another form of deception we've been subjected to.
All I can tell you is my own experience that led me to this conclusion. I used to see UFO's all the time, in fact it got to the point where I could even summon them. I used to that use an app by Steven Greer and shit worked. Steven Greer is funded by the cabal, of the top of my head it's either Rothchild or Rockerfeller, can't remember which. Ultimately one day I broke down and prayed like I never prayed before, I prayed for the truth and that if there was a God, I wanted to know Him and by the grace of God I was led to the truth and accepted Jesus. Ever since that day I have never seen another UFO nor have I ever experienced what used to be nightly sleep paralysis terror with beings in my room.
