Population of 1 because you murdered your friend?

As someone who has spent so much time in space, can you please comment on 2 things. Did you ever see anything you would qualify as a piloted UFO? Do you personally believe that we have been visited by extraterrestrials? Many former astronauts have said they've seen strange objects in space and so I am curious if you've had similar experiences and what you're ruminations on the subject are. Thanks!
