I've never seen one but a fasinating subject and one I've always been interested in. As a kid people would roll their eyes as soon as you mentioned the topic but now folk are more open to it. ..especially recently. With the American Congress hearing and David Grusch testimony and the Nimitz video and Bob Lazer. I feel vindicated and still curious about what these things are and the 'Goverment' know but the truth maybe to hard for us to handle.
I've seen a few aerial objects I couldn't identify. Not saying they were alien in origin, just craft I did not recognize. The most recent was last year, early evening during fall. I was walking, looked up and saw a bright light, like a dot, flying across the sky at an incredible rate of speed. I didn't hear any sounds, and there was no visible exhaust trail. Sure didn't look like a comet, or something burning up in the atmosphere. It moved across the sky and went beyond where I could see it in a few seconds.
