So I saw a UFO a few years back (2017)- it was a circular object that stayed largely stationary. My in laws saw it to, so I wasn’t imagining it. Obviously I took a picture, but it was so small and far away that the photo is just a white dot in the distance. Now I figure it was just a rogue cloud, weather balloon or weird atmospheric effect, but there are still phenomena that are hard to capture on camera.
