I've gone over in previous threads why no aliens are visiting us from other realms whether planetary or dimensional. The flying buildings, if they are factual, could certainly be something built by our government. The light wheels in the ocean I can't say but I haven't ruled out natural phenomena. It doesn't have to be anything revolving, it could simply be an illusion of it. I don't bother with photos and footage of UFOs because it's so easy to fake. There might be a few that can't be explained but I don't have the patience or resources to try and root them out. I think everybody can agree there are machines the govt has that we don't know about but that we are bound to see from time to time and that the govt isn't going to say, "Yes, those are ours." They have a vested interest in keeping ET going. In fact, I believe the govt started it with the Roswell incident. The best way for the govt to keep it going is to constantly deny it or simply say, "No comment." As soon as they do, we instantly resort to ET again. Talk about being controlled by Big Brother.

If aliens are visiting us, we would have proof of it by now. We have none and will continue to have none because it isn't happening. There are other aspects that could be at play such as Jung's ideas about UFOs. This has been ignored because the public is so heavily infused with ET that they can't think in any other terms. It might be a purely "psychic" phenomenon as I believe to be the case concerning Mothman, the mad gassers, the phantom shooters, etc. in which case we ignore that aspect at our own peril.
