Star Cult

Star Cults seemed to exist in an alternate time line, where Earth and it's solar system were the only things to exist in the universe. (DW: The Big Bang)

History
According to a brief conversation heard in The Big Bang, people seeing or believing in stars was common throughout history, and thus Star Cults appeared to be somewhat well-known.

In a conversation with Christine, Amelia Pond's Aunt expressed worry that Amy would grow up into joining a Star Cult and that "she didn't trust that Richard Dawkins".
