I hear lots about it, but I have yet to see real proof, so no I don’t need to adjust to the fact that UFOs exist. 8>)
There is no proof as in the capture of an unknown and previous unimagined flying craft, BUT the Navy is releasing lots of circumstantial evidence supported by eye witness accounts of Naval pilots which makes a case for an unknown craft of heretofore unknown flying and maneuvering abilities. Furthermore, this craft in question has abilities (and has had such abilities for some time) that are beyond anything the U.S. or any other government has developed.
That alone takes some adjusting to.
On top of that, these unknown craft are maneuvering dangerously close to our aircraft flying in restricted training space which happens to be located in areas critical to U.S. national security.
That takes some adjusting to, if not by us civilians, by the DOD.
