Star Cult
From Tardis Wiki, the free Doctor Who reference
Star Cults existed in an Alternate timeline, where Earth and its moon were the only planetary bodies to exist in the entire universe. (DW: The Big Bang)
History
According to a brief conversation between Amelia Pond's aunt, Sharon, and a psychiatrist, Christine, people seeing or believing in stars was common throughout history, and thus Star Cults appeared to be somewhat well-known.
Sharon expressed worries that Amy would grow up and join a Star Cult and that she didn't "trust that Richard Dawkins". (DW: The Big Bang)
