The term Anunna or Anunnaki indicates a group of gods in the Mesopotamian pantheon dating back thousands of years. For some researchers the Anunnaki were much more than myth, they were real pre-human beings who constructed many of the ancient sites in the world. A number of these ancient sites, such as Gobekli Tepe in Turkey, are thought by some to be gateways to other worlds and parallel universes which can only be accessed by those who know how.
