The discussion surrounding UFOs is one that has gone on for many a year, and there have been some pretty wild stories in that time.
One 'sighting' this year in Las Vegas shows 'shadowy figures' lurking somewhere in the shot. You can watch the creepy footage below and see if you can spot them:
The video is one of many supposed UFO sightings in Las Vegas this year, with one sighting around the incident even involving police officers.

But this particular video shows a group of people nervous as they look into a backyard behind a house, with the camera zooming in on a forklift truck which has shadowy figures lurking inside... apparently.
There was a fair bit of confusion over where the extraterrestrials are in the vid, but many people insist they're there.
One wrote: "You can see their face eyes glowing in the first tractor then look at the second one you can see it peeking if they 8to 10 ft tall."

Another wrote: "Face little left of center of circle you can see eyes and mouth."
Not everyone was so sure though, with one user writing: "What a load of b******s."
It is a bit of a stretch to be honest, no matter how hard you squint. Or maybe I just need new glasses.
Nonetheless, the video could offer fresh insight into the spate of encounters and sightings that Vegas has recently seen.

Police body cam footage emerged in June showing lights hovering in the sky before plummeting to the ground in a suspected UFO crash landing sighting.
Officers carried out an extensive search following reports of the mysterious figures, with no new evidence being uncovered.
However, an eyewitness to this suspected crash landing spoke out and claimed they witnessed the whole thing, and even stumbled across an extraterrestrial.
"My brother told me to look behind the forklift, and I did. I saw the alien creature. So when I saw it, it was a tall skinny lengthy creature," the YouTuber explained.

"He was a grey greenish colour, and when I looked it in the eyes, my body just froze. Bear in mind, I'm looking at his whole body. He has weird looking feet and a big face and eyes."
Of course, there are numerous theories about the existence of alien life. Many people believe that the universe is simply too big for us to be alone, no matter how unlikely life is to develop.
One theory about why we haven't encountered aliens is that we are being snubbed by the galactic community, either because we're too stupid, or too nasty. Harsh.

Another interesting idea is that intelligent life has evolved several times in the universe.
However, the lifespan of an intelligent civilisation compared to the universe as a whole is so relatively short that intelligent civilisations have never coexisted, as one goes extinct before another emerges.
