As 2015 ends, the bizarre parade of UFO videos only grows, with more posted to the Internet each day.

As the year progressed, we saw a purple UFO over Peru; a disc-shaped object flying behind an Argentina TV news broadcast; colorful aerial lights captured on video by a TV news station near the U.S.-Mexico border; and night vision images of Christmas-colored lights over Tucson.
Reports of UFOs near Delhi's Indira Gandhi International Airport put India's military forces on high alert at the end of October.
And while one former Air Force officer described UFO activity during the Vietnam War, another told HuffPost that the military encountered "some type of superior intelligence" that could "change size and shape."
We also learned that a Russian politician suggested aliens invented the game of chess.
And we certainly won't forget talk show host Jimmy Kimmel asking President Barack Obama about UFOs with the commander-in-chief responding, "I can't reveal anything."
Former Obama advisor John Podesta also chimed in, tweeting how he regretted not being able to secure disclosure of UFO files. As a key figure in Hillary Clinton's campaign, perhaps he'll get that chance.
Of course, no 2015 roundup is complete without mention of Donald Trump, and there was a report in August of a UFO following the Donald's helicopter at the Iowa State Fair.
