The UAC, or United Anti-Darwin Crackers, were originally formed by the Catholic Church with the intent of spreading anti-Darwin propaganda in the mid 1600's. Lots of the members of the church were realizing that they evolved from primates, which really shoves a pine cone in the ass of the creation doctrines of the bible. The Darwin philosophy soon became known as Evilution by all parties involved. To counter this new idea, the UAC decided to create a video game simulation of what would happen if people believed in Darwin's ideas, in the hopes that this would scare people back to the primitive teachings of the church. In 1681, before the computer or any video game console had ever been created, the UAC (under the guidance of the Catholic Church) created the very first version of Doom.
