According to ancient Greek mythology, when gods and people existed together, people had four arms and four legs. They had two heads and two faces. They existed happily as they were, and grew more powerful as time went on. The gods decided that the humans were getting too powerful and needed to be put back into place somehow, so they cut the humans in half. Each human now had only two arms, two legs, one head, and one face. They had to spend the rest of their lives searching for their other half to make themselves whole again. It became the point of life.
