///2. secret vehicles made by our own government utilizing a technology utterly beyond anything they're telling us about...and then flown rather recklessly over areas easily visible to the ordinary public, without apparently having any worries over "breach of security" in so doing.///

I suspect you even realized as you were typing that how baseless your speculation is. If these are secret craft, well then, of course they're not going to tell us what they are capable of--not much of a secret. Secondly, what breach of security are you referring to? Could you quote it for us? There's no breach of security. If they fly them where you can see them, it's because they want you to see them. Why? Because they have a vested interest in keeping the ET hypothesis going. So when you see one, they naturally have no comment.

Then we have to entertain the possibility that these craft are remotely guided and unmanned and so can engage in aerial acrobatics that a manned craft couldn't. We have to entertain that these craft are not craft at all but projections similar to a laser pointer. Suppose someone projects an image into the sky by some secret technology and "waves" the "pointer" all over the place--what happens? The "craft" appears to be doing fantastic and incredibly reckless maneuvers no craft can do. You can shine a flashlight on a wall in a darkened room and observe the same thing. It would account for no sound and no breaking of the sound barrier. It would account for how they sometimes explode silently. Because if that technology exists, what does it mean? It means UFOs are a big mind game being played on us. And then we have to ask why? And that starts to get a lot scarier than ETs and grays ever could be. It would also explain why we are no closer to solving UFOs than we ever were and why we have no more proof of aliens than we ever did despite what works out statistically to be about 3 million landings in the last 20 years not to mention claims of anywhere from 3 to 3 million abductees in America alone. Impossible. We are being manipulated. That could be, couldn't it? Yes, it could.

But have you dared to think these things through? No. And if you haven't, how do you propose to get to the bottom of it without at least eliminating this possibility? To eliminate it, you have to first entertain it as a possibility. That means you have to seriously consider how it could work.

Then there's the Jungian hypothesis of what UFOs are that is also, I think, highly worthy of consideration. Have you ever bothered to look into it? I doubt it because you're too busy trying to find aliens behind every rock and tree. There's nothing behind those rocks and trees. So where are you going to look now?

That's the question you have to ask yourself: "If I proved the ET hypothesis is false, what am I left with?" And I would suggest that you start looking into those possibilities.
