Some people believe that there is life among the stars and that there have been visits to earth from extra-terrestrials, others though are sceptical and want evidence to prove this.

There is one place however which is a favourite hunting ground for evidence in Peru, it is the ancient site near Nazca. It consists of strange lines covering a distance of over 200 square miles and they seem to be geometric shapes with animals intertwined in them like a snake, lizards, birds etc there is one also of a man with a halo. The site is situated between the Pacific Ocean and the Andes Mountains. It was first discovered in the 16th century by explorers from Spain.

There has been investigations into the lines within the past 50 years. Airline pilots have used them for navigation and some ufo enthusiasts say that they form some sort of navigational beacon which enabled alien aircraft to home in on Peru when they visited Nazca!
