Wandering Rocks of Death Valley, Did Aliens Cause Them To Move? March 2016, Video, UFO Sighting News.

Now I understand when a person tries to take a scientific explanation to answer a hard question, but you need to understand that their answers are not answers, but just a hypothesis, which means it is a fancy word for guessing. Let me give you my guess. I believe it is the abundance of alien activity in this area that makes them move. These rocks may move due to an underground base 3-6 km below the surface. Its perfect since few humans venture out there. Aliens can move things with their mind. Also many aliens (W56) frequently meditate, projecting their thoughts skyward. These rocks could move due to those daily meditations over hundreds of years. Remember years to them are like days to us since they live forever. Telekinesis...can occur by accident, if their meditation level is exceptionally powerful.

How do these rocks, some weighing hundreds of pounds, seem to move themselves across the floor of Death Valley? While some believe that electromagnetic fields generated by UFO's are responsible, planetary scientists reveal the actual explanation is a bit more down to Earth.
