UFO (UNIDENTIFIED FLYING OBJECTS)
History of sightings.
Some people believe UFO sightings can be traced back to biblical times. The first documented reports date back into the mid-1800s. But it wasn’t until the 1940s that sightings started to hit the headlines. In the 1970s, Erich Von Däniken wrote a number of best-selling books saying that aliens visited the Earth long ago. Highlighting biblical references to fiery objects in the sky, he even proposed that Christ may have been an extraterrestrial. Going back even further, he suggested that ancient man had been genetically altered by aliens, explaining the ‘missing link’ in human evolution.There is no doubt that unidentified objects in the sky exist. The question is – what are they? Have people witnessed alien fly-bys or something more mundane?
