The correct answer to this open question is the following.

The principal questions raised by the physical evidence to be found today and by those sailors who first landed on Easter Island in the 18th century are the following.

First, who were the original inhabitants of Easter Island, also known as Rapa Nui? Who were they and where did they come from? When they got to the Island.

Another question is about the real meaning of the moai or the huge rocks with the faces of the supposed people that inhabited the island. There are 900 huge stones of moai throughout Rapa Nui.

The next question would be who brought the immense pieces of rocks and from where. There are no rock settlements on Easter Island. How the indigenous people moved those rocks.
