Aliens have long been debated as mythical or real, but alien experts listed images that could prove that extraterrestrial beings do exist.
Alien hunters strongly believe that NASA has been hiding evidence of actual alien encounters despite clear proof that UFOs actually emerge from random places, here and outside the planet.
As reported by Mic News, six images taken by NASA strongly indicate that there are other beings beside the earthlings, including the pyramid-like structure captured by the agency's rover on the red planet.
The pyramid is believed to be a proof of an alien civilization, but NASA explained that it is only a geometrical structure. In an article by USA Today, Professor Jim Bell of Arizona State University, also a member of the exploration team, explained that the structure is only a rock.
On August 2015, CNET published an article about a mysterious female figure captured by the Curiosity Rover. The whole world was once again intrigued by the image, but experts reiterated that the image is only a rock formation.
As for actual alien encounter, a woman from California made headlines when she claimed that a two-legged creature was found in her residential property. The photo was posted on Reddit and immediately became viral.
However, some netizens believe that the alleged alien is only a deer fetus.
The most legendary sighting happened in Roswell, Mexico in 1947. According to International Business Times, a UFO craft crashed on the sight, leaving evidence of extra-terrestrial beings. Then, experts cleared out that the crashed object is not from the outer space, but only a spy-testing craft made by humans.
In the same year, old photos of an alleged alien were presented during the UFO conference. It was later confirmed that the creature is only a mummified child taken from San Francisco Museum.
Also included in the list are the 1976 UFO flying over Iran and the "Mars Henge" captured by NASA on Mars.
