The Nation of Islam believes that the white man was created in a science experiment 6000 yrs ago on the island of Patmos by a mad black scientists named Yakub--and that the Earth is 76 trillion years old.
The Church of Scientology, being a science, does not believe in such nonsensical fiction, but sticks only with proven facts such as Xenu solving overpopulation by blowing people up in volcanoes.
However, like NOI, Scientology's holy scripture also begins with: "Once upon a time, 76 trillion years ago..."
Remember the introduction for History of Man?
"This is a cold-blooded and factual account of your last 76 trillion years."
