Its very often that evidence is put forward and scrutinized. Usually it consists of pictures or video or some soil samples Etc..

What is or are the best tools to capture evidence of ufo's or Aliens ?

For example what would be the best camera to take night photo's of a ufo ?

The main thing is to keep it in focus. I think the type of camera is of little importance when the video is blurry and compressed to death. How often do you see footage of UFOs in the original size/ format? Almost never. So it would be nice to have a few good (original) quality videos/ photos.
