Since over the 1950´s the UFOs became a particular interest to some governments, specially USA´s. But with that interest they caused all kind of conspiracy theories, some of them supported by members of different areas of those governments and these are the ones we are listening to. These theories basically say that US government is hidding his deep researchs on UFOs also that contact has been established several times and even that they captured one (Roswell case) and are applying reverse engineering with it, but the government keep ignoring the subject and denying any accusation.
