Sorry, Bert. I can't almost be sure of that. In fact, given the extensive reading I've done on the subject since having those sightings back in the late 60s and putting my ear to the ground, as it were, plus hearing a great many firsthand accounts from other eyewitnesses, including people I know well, I am almost sure we have been visited by aliens. We may even be the descendants of some of them.

Yer gonna have to find something else. ;-)
