Your guess is as good as anyone's. The mystery is how these statues were created. It is said that it was near impossible for the inhabitants of early Easter Island to carve, transport and lift the statues upright with their primitive tools. Some have theorized that there were people with divine power to command these rocks to move all by themselves. This seems far-fetched, but no one can be certain that this is not true. Another theory is that aliens moved these rocks.
