Yes, there is incontrovertibly a phenomenon of unidentified aerial objects.
With our best efforts over a period of decades, some 80-90% eventually can have prosaic explanations. There is a residuum of extremely well investigated but still puzzling unsolved cases.
From the late 1940's on, there have been some high profile US government investigations involving top physicists, astronomers and military folk. They have come to the conclusions that although the phenomenon is real, it poses no threat to national security. It is a nuisance so they don't bother investigating it anymore.
Institutions such as science and government having abandoned the problem leaves the field wide open for media and public speculation. Due to the many thousands of reports occurring daily for many decades, some even going back thousands of years, it makes more sense to think of it as terrestrial in origin rather extraterrestrial. It is absurd to think that nut-and-bolt objects from another planet can burn enough energy to come to Earth so often, cavort around doing essentially nothing, and remain resistant to our best efforts to confine even one, examine and understand it. It is a fool's errand to explain the UAP as a solid object.
Accordingly, the phenomenon must be almost purely energetic (lacking mass) so that after it manifests it vanishes leaving no traces, and can never be captured and confined in a laboratory any more than could a bolt of lightning be captured and examined.
We are dealing with electromagnetic fields organized into cellular structures by DLs.
According to the evidence, they can change speed, altitude, direction, shape, size and color without a problem.
Yet they don't attack and do usually run away when probed with radar.
There are baby-sized versions of UAP which occur regularly in particular places on Earth, such as Hessdalen, Norway and the Yakama Indian Reservation, Washington State, USA.
Professional scientists have studied these junior-grade versions of the phenomena for decades now. Some of their reports are posted in the "Electrical Eccentricity?" thread. It's pretty clear they have the idea they are studying an electromagnetic plasma phenomenon.
