If you are interested in the UAP/UFO issue I would recommend watching this presentation with Dr. Steven Greer and witnesses coming forward.
Dr. Greer is not a "hero" in my opinion, I enjoy the guys work, but have seen that he can be viewed as a quack and hasn't always been honest in his stories of what he has done, who he has briefed and so on.
However, the UAP issue is increasingly being featured in the media and whether you think it's a psyop (Project Bluebeam) or real it is worthy of discussion.
I have seen a UAP my self several years ago at a camp together with five other people and am convinced that there are visitors. It is not clear to me now if it was human or not though. With info coming out about reengineering alien technology it might have been "one of ours".
Anyway, not saying I trust all the info in the video but it is interesting not the less.
