Theia’s Earthlings is inspired by the great Greek Goddess Theia (Known as divine sight and light), and also heavily inspired by one of the great theory in science, a proto-planet named Theia crashed into Proto-Earth billions of years ago, becoming the reason why Earth has life and is the only habitable planet in the solar system. “Earthlings” is another term for people - humans, mortals, and all. In this game, it shows two different lives, two unique earthlings, named Arri and Tina. A college student and a high school student, each having different roles and different paths as the story goes, but still sharing the same theme. Arri’s project requires making a campaign speech about an environmental problem we face today. Meanwhile, Tina’s project requires writing an essay regarding the causes and solutions of that same environmental problem.
