A group of experts seems to have found the way Rapa Nui people, also known as Easter Island, constructed the Moai statues. This new notion is closely tied to the island’s difficulty in finding water. So Carl Lipo of the University of Binghamton’s research highlighted all of the issues these people faced in ancient times.
The islands had no rivers so it was natural for the early people to attempt to build water ponds. This perspective suggests that these statues could have been watermarks. This means that these statues were able to help people find water reservoirs. Each statue also indicated the location of these reservoirs.
However, while this explanation is extremely plausible, Lipo is unsure whether this was the underlying motivation behind the sculptures’ construction or for some other undiscovered purpose.
It is clear that the statues represent the large population of the island at that time. Their work has also survived to this day.
