re:It seems obvious that you misunderstand me totally.
You wrote:
It is folks like you that claim that a) they are up there at all, and b) they are staying up there using some kind of miraculous science.
First of all for your a) There are all kinds of things flying in the air that people have seen and could not identify, this I believe. I also believe that it is not impossible to travel in space, I also believe that it is not impossible for human beings to develop devices that will carry them to other planets in other solar systems.
Sure, it may take a long time before that happens but humans have the ability to create, develop, and construct almost anything they can imagine. (Pathological Skepticism suppresses such development.)
If something is not impossible for us to accomplish then why would it be impossible for some other beings somewhere else in space to do so. And yes I believe that we are not alone in this universe.
As for your b) I have never indicated that: "they are staying up there using some kind of miraculous science." I am totally convinced that "they" use science that is quite "normal."
It is simply that we do not understand everything that there is to understand about the laws of physics.
How fast could a craft accelerate if the air resistance was removed from the front of it?
Did you open the link to the "hovering" saucer shaped model that is internally powered.
That "saucer" uses "conventional" methods to make it fly, yet there is no visible rotors or engines.
