My concern here is that if these testimonies can’t be linked to evidence, the entire subject will be once again be discredited, goodwill from legislators will evaporate and the status quo will remain - that being UAPs being genuine alien devices or no.

The part that never adds up to me is the complete lack of concrete evidence in the open (when there is ubiquitous technology for detection in the hands of the public), or the implied astonishing competence of governments and agencies cooperating internationally to keep alien intelligence hidden. We couldn't prevent a pandemic, have lost nuclear weapons and are watching the planet die due to carbon emissions… yet somehow the alien-intelligence-suppression-network works?
