Dr Roger Lier, a qualified surgeon, claims to have removed a total of 11 implants from aliens. He has sent them off to "one of the most abvanced labs in the world" and the people who did the tests were stumped by it. I saw this clip of him which, i think, is going to be aired soon in an episode on the discovery channel, the electron microscope images do look organized on a very small scale. Has he been discredited? Theres alot of stuff about him on certain UFO sites, its just hard so separate the garbage from the facts.
