Armed with millions of available cell phone cameras and digital cameras, people are looking to the skies around the world, and posting images of apparent UFOs on YouTube every day.

It's about time the FBI helped out with sifting through it all. Or at least former FBI Special Agent Ben Hansen, who now makes a living uncovering the truth behind strange and bizarre sightings.

"I think that having a background in formal investigation helps in a logistical part of how to manage a case, and also gathering information," Hansen told The Huffington Post.

As the lead host and investigator of the Syfy Channel's "Fact or Faked: Paranormal Files" series, Hansen, seen at right, uses his FBI-trained skills to debunk fake material and search for the truth. He says most UFO sightings are easily explained.

"It probably falls in the range of about 95 percent. When you actually have a photo or video, I would say the percentage of the unexplained increases a little bit. However, the biggest factor, I think, in the increase [of claimed UFO videos] is due to the availability of computer graphic software."

Hansen looked carefully at several videos for HuffPost Weird News and offered his expertise on whether they're fact or faked.

One video shows three lights in a triangular pattern over an east London power station in August. The lights appear to merge then suddenly vanish in a bright flash.

"The guy who took the video admits in his comments that there are some video cuts, because of his swearing and bad camera work," Hansen noted. "When I go frame-by-frame on this, it's only one frame that flashes out, and it's very easy to replicate just by doing a little artwork around the clouds.

"I give a bit of attention to people's reaction -- they react to different situations in a whole myriad of ways. But I do feel this was a little underwhelming to them. It didn't feel very congruent. When you see something flash out like that, I would be screaming, myself.

"I would give it a 95 percent probability that this has been computer generated," Hansen concluded.

The next item is a video from Russia titled "Shockingly real!" It allegedly shows a group of glowing orbs over a house while other individual orbs move through the sky. They seem to pass behind trees and a power line.

"The title itself is interesting to me," Hansen explained. "There's a tendency for people who lie to over-compensate when presenting a story. By using just the words 'shockingly real,' they're more concerned in convincing you that something is real, rather than just presenting the facts to you."

The former FBI agent points out that one of the orbs in the Russian video actually appears to pass in front of the power line in the picture, rather than behind it. He calls this technique rotoscoping.

"In rotoscoping, what the editor has to do is to basically trace an outline for an object, and they extract that object to another layer of the video. You tell the program, 'I'm extracting this part of the power line,' so when the animated light comes by, I tell the program that this is now a second layer, and it will go behind the power line."

But because Hansen thinks this video didn't quite get it right, what's his "Fact or Faked" legitimacy percentage?

"I'd say this is 98 percent faked. I also really don't like when people put music and theatrical editing behind a video. All I want to see is the raw footage.

"And the other thing about this is that it's pretty typical of some objects that we see, like sky lanterns. What I always tell people is if you've gotten as far as you can with the video or the evidence and you can't figure out the story, figure out the storyteller."

Hansen also likes to remind people that, with sufficient experience, a 14-year-old can turn out work that's comparable to a professional, using the same software.

In the following compilation video, Hansen suggests that the camera movements in some of the examples "are more difficult to replicate and the reactions seem a little more genuine."

Finally, Hansen offers advice to those who continue to fake UFO pictures or videos.

"For the hoaxers, it's fine with me to demonstrate your skills, if you want to take on the UFO or paranormal subjects, but do it ethically.

"The fact is, this phenomenon is real -- it's really happening, and new technology helps us sometimes to get closer to it. But because of the ease of which we're able to now create things ourselves, it's also hindering the field."

Most UFOs can be easily explained. Take a look:

  • Melbourne, Australia, Feb. 2013

    This is a composite image of how three alleged UFOs maneuvered about in the sky over Melbourne, Australia, in early February, 2013. The final verdict isn't in yet on whether they're birds, aircraft, balloons, bugs or something truly unidentified.

  • Lanterns

    These candle-lit Chinese lanterns can rise high into the sky and are often mistaken for UFOs.

  • Exploding Weather Balloons, Not UFOs

    On Dec. 20, 2012, a bright, circular object (pictured at the top of this composite image) was videotaped exploding in the skies above Sacramento, Calif. It wasn't immediately identified, resulting in speculation that it was either an alien spacecraft, military top secret weapon, runaway planet, North Korean satellite, among others. Within a short period of time, it became apparent that this was a weather balloon. The bottom part of this image shows such a balloon as it ascended over Tampa Bay, Fla., on July 2, 2012, and exploded in an identical manner as the Sacramento object, probably much to the dismay of all true ET believers out there.

  • Boomerang UFO composite images -- 10-5-12

    This is a composite of images shot by two eyewitnesses of a boomerang-shaped UFO they reported seeing over their Burbank, Calif., home on Oct. 5, 2012. Mutual UFO Network photo/video analyst Marc Dantonio concluded the object was likely "a balloon, floating on the wind that has collapsed in half."

  • Changing UFO Pattern -- Warren, Mich. 1-10-13

    This four-image series of lights in the sky was recorded over Warren, Mich., on Jan. 10, 2013. The lights were seen changing into several patterns. The most logical explanation for these types of UFOs is a series of balloons or lanterns.

  • UFOs Over Earth

    This composite image shows four different times that alleged UFO were photographed above Earth by either space shuttles or the International Space Station. The big question is whether or not they are truly unidentified objects or if they are more likely reflections from spacecraft windows, meteors or fast-moving spacecraft-generated debris.

  • Cincinnati Skydivers NOT UFOs Sept. 28, 2012

    On the night of Sept. 28, 2012, a group of strange-looking lights appeared in the sky near Cincinnati, Ohio. First there was one, then, two, then three lights, slowly descending. It turns out, however, that these lights were originating from a group of skydivers performing a pyrotechnics jump at the La Salle High School homecoming event.

  • Weather Phenomenon

    Some UFO sightings may be due to a natural phenomenon known as sprites, like this one shown from 2006. "Lightning from [a] thunderstorm excites the electric field above, producing a flash of light called a sprite," said geophysicist Colin Price.

  • Clouds

    Clouds: Saucer-shaped or "lenticular" clouds that form at high altitudes have been confused with UFOs.

  • Blimps or Advertising Balloons

    Blimps or advertising balloons: These can look like flying saucers from some angles, especially at night.

  • Sunken Ship in the Baltic Sea

    On June 19th the Swedish-based diving company Ocean Explorer discovered something they've never quite seen before. They were exploring in the Baltic Sea between Sweden and Finland looking for sunken treasures when a very unusual image suddenly appeared on the sonar. A 197 feet diameter cylinder shaped object was discovered at the depth of approximately 275 feet which resembles the Millennium Falcon from the movie Star Wars.

    Pictured is a quad copter -- a deliberately manufactured UFO created by special effects wizard Marc Dantonio for a National Geographic special, "The Truth Behind: UFOs," which aired in December 2011. On the left is what the small device looks like resting on the ground, measuring 4 feet in circumference. At right, is how it appeared behind a tree in the night sky.

  • Police Dashboard Camera In Texas

    In February of 2012, this fireball was captured by a Texas police chief's A dashboard camera. F.A.A. say this was probably a meteor, falling to Earth. .
