The problem is the terminology doesn’t match. When others use UFO to refer to any unidentified object, and they have proof, that proof doesn’t mean alien UFOs have proof.
UFO absolutely holds connotations of aliens, and has for half a century. That’s why the term UAP began use, to separate official documentation for the implication of aliens. And OP clearly referring to aliens.
