As the number of unexplained UFO sightings across America grows exponentially, something tells me that we may get the answer to that question sooner rather than later.
Just take a look at this amazing footage that was filmed along the Las Vegas strip over the weekend.
In the video below, a series of lights dances across the sky making various strange formations. At around the 2:15 mark, things really get a little big crazy.
As the uploader points out, the rest of the world seems oblivious to the light show hovering above, which is millions of times better than anything you could ever see in Vegas.
Check it out below.
