While I was watching a UFO/JFK video on YouTube, I suddenly realized why the CIA would have an interest in UFOs and aliens. They are a foreign power by definition because they come from outside of Earth. That's inside of the CIA's foreign intelligence mission. That's all I have to say. JFK's Memo to NASA...

When comparing alternative explanations, remember, it a theory being considered as an alternative to life from outer space. Since that's the alternative, and there are so many barriers to that, I think I lean a bit more toward a breakaway group of humans who secluded themselves from the rest of humans a very long time ago and evolved independently. I find it interesting how many of these sightings involve moving from the air to deep underwater. Congress implies that UFOs are "non-human" in origin 'the House and the Senate have continued to work on new legislative language regarding the Pentagon’s investigation into the strange objects being seen in the skies over our restricted military airspace. But it’s no longer just the skies. As the always-reliable research journalist Douglas Dean Johnson recently reported, multiple defense and intelligence bills are currently moving quickly out of the appropriate committees and heading for floor votes where they are expected to pass with little or no objection. One such bill that Johnson highlights redefines the meaning of UAP (formerly Unidentified Aerial Phenomena) to be, “unidentified aerospace-undersea phenomena.” The language also includes references to “transmedium” vehicles capable of transitioning from space to Earth’s atmosphere and into bodies of water. Dean’s full analysis at the link is well worth the time to go through.' We have nothing that can seamlessly transition from from Space/Air/Water and operate like these things can. "Congress specifies that the new definition of UFO “excludes man-made objects.”'
Well, if you want to argue that the UFOs are man-made, then you should know that I heard that the crop circles are actually encoded messages in some sort of time war. And someone has been using supercomputers to try and decode them. As for whether some of the origins of UFOs are from the stars or not, I seem to recall someone saying that not all UFOs are acting in a way that is consistent with what we might see if all UFOs were visitors from the stars. That is, some not all are not aliens. But I haven't really looked into it.
