8Nazca Lines

The Nazca Lines are a series of hundreds of ancient geoglyphs located in Peru. These include depictions of animals, birds, fish and humans, along with simple lines and geometric shapes. Some of them are over 600ft. across and can only be viewed properly from the air. This has led to speculation by the Ancient Astronaut crowd that the ancient Peruvians were capable of advanced flight, or were trying to communicate with beings that were. Scientists have claimed the lines were of a spiritual significance, possibly pertaining to the availability of water. Also, historians have since recreated similar lines using primitive techniques without aerial assistance.

8 納斯卡線

納斯卡線是位于秘魯的一系列數以百計的古代人形石刻。這些線條組成的圖案有動物、鳥類、魚類及人類的形象，由簡潔的線條和幾何形狀組成。有些圖案寬達600多英尺，只有從空中才能完整觀看。這引起了古代宇航員理論擁護者的猜測：古代秘魯人掌握了先進的飛行技術，或曾試圖與掌握這些技術的生物交流。科學家們聲稱，這些線條具有精神上的意義，可能與水利有關。同時，歷史學家也采用原始技術在沒有航空手段輔助的情況下重新創作了一些類似的線條。
