Do you think aliens in ufos have visited Earth? (And all things UFO)

The self appointed UFO experts I'm referring to are the people like Jeremy Corbell. I don't doubt the experiences of people like your friend or the naval aviators. The interviews of Bob Lazar are the most convincing ones I have listened to or watched. My main issue was with the series itself. I found it unfocused and half baked. I would have liked it more if they focused on the credible events themselves.
