Nazca Lines are the
most outstanding group of geoglyphs in the world 
. Etched in the surface of the desert pampa sand about 300 hundred
figures made of straight lines, geometric shapes and pictures of
animals and birds and their patterns are only clearly visible from
the air 
.
Could these geoglyphs
be effigies of ancient animal gods or patterns of constellations? 
Are they
roads, star pointers, maybe even a gigantic map? 
If the people who lived here
2,000 years ago had only a simple technology, how did they manage to construct
such precise figures? 
Did they have a plan? 
If so, who ordained it? 
It all seems
so otherworldly 
. To comprehend the Nasca lines, created by the removal of desert
rock to reveal the pale pink sand beneath, visitors have proposed every
imaginable explanation from runways for spaceships 
to tracks for Olympic
athletes 
, from op art to pop art, to astronomical observatories 
.
It is believed that the geoglyphs were built by a people called the Nasca 
but why and
how they created these wonders of the world has defied explanation 
.
