Jack: These caves make too good a shelter just to be used for burial. Adam and Eve, they must have lived here. Their plane crashed or maybe they were shipwrecked. Probably when they found this place, they knew they could survive here. Unlimited supply of fresh water; Tree canopy keeps the temperature down, shields out the sun; Openings are narrow, easier for protection against predators. We don't need to bring water to people. We need to bring the people to the water.
