I'm gonna propose to the alien believers a different explanation of UAPs: they're black projects. Yes all those physics defying things are man made, and they probably have an understanding of physics we don't currently know about in the wider public.
Technology trends exist. We can see them. It's no wonder that every generation's stereotype of unidentified craft always always always mimicked the latest generation of military flight tech. That's what's been true since the inception of the whole thing. It's true today too, thirty years from now we'll get a public look at the crafts they're testing out in the skies today. Be that because they get used or because they become obsolete. Thats how it goes.
So why the hearings in Congress? Because they're black projects. We're talking trillions in this rabbit hole. Congress very much has an urgent want to understand what they military might be keeping from it, vis a vis private contractors. We're talking multiple times the budgets of nation-states and we're getting receipts that are basically "trust me bro"s.
But Congress can't very well tell the truth of all that without undermining the American military, and thereby America itself. So they go along with the same "aliens" reasoning, "uhh yeah, let's go with that, okay", and keep pressing for more information.
Is that crazy? Yeah, you bet. But it's no crazier than believing all that and that there's aliens. Because the alien conspiracy crowd asserts virtually everything I just said, just, with aliens. Aliens aren't necessary for any of it though.
In the history of nations there's never been a more sure-fire way to lose democracy than making an enemy of the military complex propping it up. So Congress ought to be careful too, keep a little plausible deniability for themselves.
