We're already convinced that aliens exist, so it's not like we need any further proof. But these clips of identical UFOs hovering in the sky over Brooklyn and San Francisco blew us away. All hail our alien overlords! (The videos are a bit NSFW, by the way, due to some UFO-inspired potty mouth.)

The bright, round lights were first spotted in the sky over Prospects Heights in Brooklyn, New York, on Dec. 3. Amateur video shows the glowing orbs slowly moving in a triangular formation until they wink out one by one.

Several days later on Dec. 8, a man named Enrique Barrios captured a similar-looking set of objects in the sky over San Francisco. Like those witnessed in New York, these orbs inch across the nighttime sky until they disappear.

Barrios insists the lights weren't a figment of his imagination and were witnessed by multiple people. "I wasn’t sure if at first if it was another Tequila-hazed mirage, but myself and a few bystanders were all in complete awe at the lights we saw on Valencia," he said. "I am 100 percent sure this was a UFO. You folks be the judge."

What do you think of these strange lights? Are they really alien spacecraft or is there a more earthly explanation, like flares or Chinese lanterns? Check out the videos below and decide.
