The demons deceive. If they need to dress in neon suits, they will do so. They need a narrative that we will buy to go along with them and a space federation is right up our alley.
I do believe in other creations, but I don’t believe that we are allowed to see them just yet. The reason being is because of the sin issue. We are an object lesson for history and everybody to see what happens if a planet has chosen to live without God.
Aliens would complicate things, so I don’t they are permitted. Once the sin issue is resolved, we will see everything.
You need to fear our own leaders who are destroying our civilization right now. The apparent ETs have been here a very long time; and, they aren't the ones who are busy with that destruction. A proper perspective is in order.
