I’ve got no question that alien life exists and that at least one species has visited us. I know this because of my own encounter. I also think ourselves from the very distant future visit us and actually are the people involved in abductions.
But in spite of relating my own experience and my ongoing interest in the subject, I’ve never been visited by the “Men In Black”, so as far as UFO / Aliens go, I’m disinclined to believe they exist, although they were fun movies.
Real Men In Black do exist but their job relates to nuclear materials and incidents, not aliens.
If anyone out there has had a Men in Black encounter, I’d be real interested in hearing the details.
