According to an email published on the website UFOSightingsDaily.com, a website specialising in UFO sightings, the mission is part of European Space Agency and American space agency Nasa cover-up to disguise the comet's true alien nature !
Allegedly, a secret whistle-blowing employee of the ESA, sent the email. The person accuses the agency of "blatant cover-ups" and attaches photos which claim to reveal the "true inner workings of Comet 67P".
Here is what the email says: "Do not think for ONE MOMENT that a space agency would suddenly decide to spend billions of dollars to build and send a spacecraft on a 12-year journey to simply take some close-up images of a randomly picked out comet floating in space.", as reported by Guardian.
"Comet 67P is NOT a comet," says the letter. "Some 20 years ago Nasa began detecting radio bursts from an unknown origin out in space. It would later be known that these had likely come from the direction of the now named comet 67P. It does show signs on its outside of machine like parts and unnatural terrain."
The letter says that the signals were some kind of greetings to humanbeings from the aliens as if those were warnings, ESA wouldn't have let Philae land on the surface of the comet.
This is not the first time extra-terrestrial conspiray theories surrounding comet 67P has emerged. The Guardian says that in September, BPEarthWatch had published a video showing "brand new, hi-res" images taken from the Rosetta spacecraft, which showed two UFOs flying over the comet and a transmission tower-like structure built on the surface !
The article further says that ESA's confirmation that the comet had been emitting a "mystery song" has strengthened theories that the comet is in fact an alien ship. Experts on UFO occurances say that the 'song' is a mode of communication between aliens. It could be a form of telepathy put into primitive radio signals.
