									All over the thirty miles and more of desert 
									where ground-drawings can be found, these 
									show always the same basic forms. The same 
									kind of quadrangles, triangles, zigzag- and 
									oscillating lines on large and small scales, 
									the same starlike centres can be found 
									everywhere, on vast plains. They are one 
									single creation and are, together with the 
									animal figures, quantitatively and 
									qualitatively the most outstanding of all 
									works by ancient Peruvians." 
									Maria Reiche, Mystery on the desert. 
									 
									Scientists made some researches about 
									the lines, which were found in Peru, in 1926 
									by two archeologists near Nazca town and 
									which are like triangle, quadrangle, spiral 
									and animal shapes. Some of them claimed 
									that, some of the lines mark the solstice of 
									winter and summer, and some of them claim 
									that, they are a giant calendar. Some 
									scientists and adventurous claim that, these 
									lines were made for UFO's. 
								
								 Here are some 
								theories:
								
									- 
									
									Astronomical 
									observatory: Many of the lines point to 
									constellations and can be tied to solstices 
									and equinoxes.  
									- 
									
									Water: The 
									desert-dwelling Nascans obsessed about 
									water, and the lines could map underground 
									sources.  
									- 
									
									Labyrinths: Each 
									figure is constructed from a single line, so 
									they could be walked during ceremonies.  
									- 
									
									Sports stadium: 
									The Nazcans were great athletes, the 
									thinking goes. Maybe the lines were running 
									tracks.  
									- 
									
									For tribute: The 
									markings can be seen only from the air, 
									making them messages to the gods.  
									- 
									
									UFO landing 
									strips:  Erich Von Daniken popularized 
									this theory with his best-selling book 
									Chariots of the Gods?  
									- 
									
									To measure 
									rainfall.  
									- 
									
									Areas for 
									rituals and sacrifices of animals.  
									- 
									
									A memorial area 
									for the Great Flood. Every culture has it's 
									own Flood Myth, and this could be their 
									tribute to the flood  
									- 
									
									They are markers 
									for underground waterflow. The lines were 
									representations of flow pressure, direction, 
									etc.  
									- 
									
									They were used 
									for dowsing purposes.  
									- 
									
									Each figure 
									could be markings of different clans around 
									the Nazca plains.
