A new video that surfaced has a lot of people talking and speculating. A man was out riding his bicycle while a storm was approaching, then a strange light caught his eye so he pulled out his phone and "shot this video."

As you can see clearly in the video below, what appears to be light  being emitted from above the deck of clouds probably has a very big light source, and the source is unknown. It appears as if a spotlight is being waved around from above the cloud, or is it an alien spacecraft with some pretty "big" technology? It could even be military, or even a weather phenomenon.
