I saw this on UFO Hunters a few months ago, the implant in the one person's body actually looked like it was moving. Even the investigators said it was, but you could obviously tell it was due to the Doctor pushing on it through the skin.
The Alien implant in the picture was found in a patients mouth after an x-ray test by her Doctor. Now why would anyone want to stick something like this in her mouth. For many years, this 44-year-old patient appeared to be having strange dreams involving visitations of creatures and other representative associations with the abduction phenomena. This almost seems like solid evidence, but nothing was released what the object was made out. The information that was released stated that the implant was bronze in color and seems to have thickened and beveled ends. It is very lightweight and highly magnetic. Tests will be done later in the year with atomic force microscope for electron microscopy.
I'm still waiting on some sold proof...
