Listen to the CIA guy—I gave you the links.
He is talking about his personal experience.
His personal experience is not a “conspiracy theory”.
In fact most contactees are simply talking about what they experienced—that is not a “conspiracy theory” either.
You can believe them or not as you choose.
People speaking the truth as they experience it deserve our respect imho—”conspiracy theory” is a cheap and undeserved shot by those who have not had the experience.
I have always been unable to verify the bonides of such folks, and just being in the intelligence services is not in itself verification of the actual role someone had. For instance, Jim Serivan who was in the Clandestine Services division at the CIA tells us nothing about if his role there intersected with anything having to do with UFOs. He unsurprisingly does know alot about how things in the intelligence services work but that also is not verification of anything in his official work that was related to UFOs.
In so many cases we are left with trying to just take what folks say at face value.
