According to Wikipedia, “An unidentified flying object, often abbreviated UFO or U.F.O., is an unusual apparent anomaly in the sky that is not readily identifiable to the observer as any known object.” While many associate them with alien spacecraft or inter-dimensional vehicles, the majority of the ones that pop up on YouTube are either hoaxes or explainable events.

Every month, we document the best videos from the previous month by posting the compilations by AnonymousFO. Somehow we missed the “year in review” video that they released last month, so to correct that, here’s what 2012 looked like in the world of UFOs in 2012. Will 2013 see even more UFO videos popping up? You bet it will.
