but if they are not mystical beings, how do they do to rule out physics laws?
It is amazing to me how a homo-centric viewpoint can stop the imagination from contemplating the idea that we don't know much? And how such a viewpoint has created laws of the universe which must be adhered to? I don't even "know" what these UFOs are, but I am very skeptical of the explantions for the reports I've read about them. The comfortable world of conformity is not my cup 'o tea, pdela.
Doubt is at the root of skepticism and critical thinking. We should have more of it.
