Nazca lines are a complex of strange lines and ornaments that are situated on the ground. Undiscovered until the airplane because they can't be seen from the ground. No one can really explain who created them , but one thing is for sure - it is not natural, because those are not just the simple ornaments - there are birds, human figures, identical ornaments and lines. Longest of them are even two hundred metres long. Also the strange thing is that the descriptive animals are not from South America. There are orchas, sharks, monkeys that are living just in the jungles and so on. There are theories that the Nazca lines are the work of a civilization that existed even before inks , a clever and civilizised one. Also it is said that this civilization created the incredible Machu Pikchu which is actually considered as the masterpiece of the inks. Moreover, theory says that the inks were just the protectors of that civilization’s traditions and beliefs. Some people even says that this civilization was so clever and developed that one day it just destroyed their world and then they encoded the warning to us - their descendants not to make the same mistakes.
