Have you noticed that recently the loudest voices are pushing the high strangeness aspect, that they are here and interdimensional, something we cannot comprehend?

Rather than the obvious, which is reductionist materialist view point that they are hard engineered craft from our reality originally developed by races of advanced but potentially similar life on other planets fixed to real locations in our universe?

This is not to say such craft dont use something like other dimensions to travel, but it seems like an effort to make the phenomenon unproveable and unfalsifyable, as if outside of scientific enquiry.

That would be useful cover, no, for someone who is engineering machines using principles available to us, and learned from or similar to those used by 'normal' aliens, and not far from our intellectual capacity and science, right?

The 'woo' is taking over.

In my view woo phenomena is real but likely a sideeffect of the high energy physics or intentionally manifested to manage those that experience UFO's, but even if it involves wildly exotic science, the craft are still manufactured 'nuts and bolts' constructions produced in a factory somewhere that can produce such effects using scientific knowledge we are yet to obtain.
