Scientologists have this dude, Xenu, who, 75 million years ago, brought billions of people to Earth in DC-8 -like spacecraft, stacked them around volcanoes and blew them up with hydrogen bombs. Their souls then clustered together and stuck to the bodies of the living, and continue to wreak chaos and havoc today. Pretty extreme way for an advanced technology to deal with overpopulation, but there you have it.
I'll stick to pirates, myself.
