Please answer the following question: Read the following paragraph and extract the answer for the question: Whose journey is Heyerdahl emulating to prove they could have reached Easter Island?  The film is the dramatized story of Thor Heyerdahl and his Kon-Tiki expedition of 1947. While the prevailing theories of the time held that Polynesia had been settled by peoples migrating from the west, Heyerdahl, an experimental ethnographer and adventurer, sets out to prove his theory that people from South America settled the islands in pre-Columbian times. Noting similarities between statues found in South America and the Polynesian moai, Heyerdahl's theory about the origin of the Polynesian people is bolstered by Polynesian folklore that tells of an ancient tribe called the Hanau epe that are said to have once inhabited Easter Island. While most experts hold that such a voyage across the vast ocean is unlikely to have ever been successful, in order to illustrate that there were no technological limitations that would have inhibited the ancient peoples from making the journey, Heyerdahl puts his theory to the test and builds a balsawood raft using the same techniques that would have been utilized 1,500 years ago by the indigenous peoples of the region. Though he himself cannot swim or sail, he sets out on the treacherous 4,300 nautical mile–journey across the Pacific from Peru to Polynesia aboard the small raft, along with his crew of five men (and a macaw named Lorita). During the three months aboard the primitive vessel named after Inca god of sun and storm, Kon-Tiki, the crew's scientific reenactment of the legendary voyage from the coast of Peru to the Polynesian islands is met with setbacks in the form of storms, sharks, and other perils of the open sea.

the Hanau epe
