Inspired by the historic landing of the space probe Philae on Comet 67P/Churyumov-Gerasimenko, Cosmic Cowboy explores the origins of the universe beginning at the Big Bang when the universe is formed by the mating of the Sumerian gods, Tiamat and Apsu. It traverses the mystery of time and space, through wormholes, black holes and alternate universes, until it comes full circle into the ultimate mystery - the human heart. Tia, Tiamat’s daughter, befriends the robotic probe and together, they confront the Astronaut from the spaceship Mayflower sent to retrieve the robot and to capture Tia, the first extra-terrestial known to us.
