They aren't fake if that's what your thinking. The aliens are real. There is a mountain of evidence that proves it. For those that know, listening to skeptics is laughable. For those that don't know, but believe, those people have seen enough evidence to jump that hurdle. For those that don't believe or completely deny the existence of UFOs and/or ET are thoroughly brainwashed or getting paid. These things are not billions of light years away. They are right here in our solar system and have been visiting our planet for 100,000+ if not millions of years. I personally believe we humans are their experiment in genetic engineering. As to what purpose I can only guess.
