There have been countless conspiracy theories and "definitive" videos that attempt to prove alien life and that UFOs exist, but this latest video even has experts stumped. 

The footage was captured by two brothers, Quintero and Jose Salvador near the border between Mexico and Texas, and appears to show a shiny object floating in the sky, but given its shape and flight pattern, it's clear that it's something very unusual. 

The footage was captured on June 29th in the afternoon, and was shared on YouTube by UFO Sightings 2015, where experts offers their commentary on the footage, proclaiming that it is "incredible", and that the flying saucer was about the size of an SUV.

They do admit on the description of the video that it could be a drone, but that it is still pretty unique and can't simply be explained by that alone. Other comments on the video have stated that it's a remote control model of some description, and that the video is fake, but the expert in the video seems pretty convinced that it isn't a hoax.

That said, we are talking about a video from a self-proclaimed UFO expert, which is akin having a PhD in Unicorn Studies...
