The Bible mentions unidentified flying objects as flying scrolls, metallic, and finally clouds. Since the invention of YouTube UFO channels are ubiquitous and people are inundated with the unexplainable and CGI. We know CGI was not the driving force behind UFO encounters in ancient times because they were witnessed and recorded in the Bible. In my opinion, the most mysterious of these UFO encounters are the cloud UFO. Why? Well, because they are clouds that move with intelligence. You never know what is in the cloud and even Alexander the Great had an encounter with cloud UFO in battle. The cloud UFO has even appeared on ancient coins so it certainly has a storied past. Below is a video which of a recently captured cloud UFO and post to YouTube.
