aliens among us

About half of all Americans believe that aliens have visited this planet, in this blog post I will touch on the evidence and my opinions of this idea. Evidence of possible alien contact goes back thousands of years to ancient cave pantings of flying discs to drawings in mexico of spacemen and flying saucers. One of the most famous supposed ancient alien messages are the Nazca lines in Peru many people think they were made to signal the aliens although there is evidence that the peoples that made them had hot air balloons. Many people today have supposedly seen UFOs, most of them are bogus but there are a few interesting ones including the Arizona lights and those strange radar sightings over Alaska. One of the most interesting things about a lot of the UFO sightings is that many of the interesting sightings are triangular or circular in shape, the Arizona lights which thousands of people saw were triangular in shape. So if aliens really have visited us I would imagine that there ships would be triangular or saucer shaped. My personal opinion is skeptic I think that most UFO sightings are complete bogus but there are a few that interest me, but just because you cant explain something or you don't know doesn't mean it has to be aliens.
