@edgarblythe,
I think we should develop a new standard for validating the evidence of UFO's and Aliens. From now on it shouldn't matter what it looks like or what it's doing or even what it's made of... if it doesn't teach us something that we didn't already know, then it doesn't matter.
So no matter how weird something looks, unless it's made of a different DNA which teaches us something new, it's not an Alien. Or if it looks like a UFO and lands in your back yard and you take thousands of perfect photo's, if it doesn't show us a new form of physics that improves our scientific knowledge, then it's not a UFO.
It seems to me that the only real reason for proving UFO's or Aliens is to help us learn something new, so if the thing that is discovered doesn't teach us something, then I don't really care if it's an Alien or not.
