Determining how they were made has been easier than figuring why they were made. Scholars have theorized the Nazca people could have used simple tools and surveying equipment to construct the lines. Archaeological surveys have found wooden stakes in the ground at the end of some lines, which support this theory. One such stake was carbon-dated and was the basis for establishing the age of the design complex. Prominent skeptic Joe Nickell, refuting the "ancient astronaut" hypothosis of Erich von Däniken, has reproduced the figures using tools and technology available to the Nazca people. Scientific American called his work "remarkable in its exactness" when compared to the actual lines.[14] With careful planning and simple technologies, a small team of people could recreate even the largest figures within days, without any aerial assistance.[13]
