One summer my father and I planned a motorcycle trip to Wyoming for the UFO convention. We thought it would be nice scenery and we'd get to see what this UFO "thing" is all about. All I have to say is that I sincerely believe that something is happening to poeple, and these people sincerely believe it was aliens. There are enough sighting of UFO's that it cannot only be explained by mass hysteria, swamp gas, or secret government projects, to give many of them some weight, in my mind.
However, you've got to test the spirits in all of this. God said His Word was His Gospel to this world. And in this gospel the ONLY interaction we have with "extrsterrestrials" according to the Word is when they are angels, NOTHING about interaction with any other "created beings". So, these "aliens" are not from God, because they pretend to be something else, contrary to the word of God. And now, It sounds like ithis crap starting to fool some folks.
