The Nazca Lines

Nazca Lines
The Nazca Lines are ancient geoglyphs. wich They (The geoglyphs) are in the desert of Nazca, Perú. They are composed by some hundreds of figures from simple single line designs as lines to complex zoomorphic, fitomorphic and geometric figures.  Theses designs are drawings on the land surface.  Some drawings represent  birds, llamas, jaguards, monkeys andor  humans. These figures are big and can reach up to 365 meters.
Contrary to popular belief, Nazca Lines are not only appreciated from the air, but also, they could be easily seen from the surrounding hills.??? (<---This sentence does not make sense-Please re-check it) As the years pass, some flights over the Nazca Lines have suffered different emergencies, being some of them fateful (some flights?  I thought we were talking about drawings). Despite this, there are a lot of tourist who continue to visit this incredible place every year.
The Nazca Lines were declared as a World Heritage (Is this a proper name?). in 1994. However, in recent years they have suffered serious damage by the building of Pan-American highway.
The most damage has been produced by human .  This includes causes as invasions, illegal mining and or looting.
Today, many research reveals different theories  hypotheses about Nazca Lines and the most accurate logical is: that these lines were ceremonials and they were related with to water.
Without a doubt, This place is a big mystery for the whole world and it will continue surprising us.
