Earth. All 76 planets Xemu controlled were overpopulated including earth. Each planet had on average 178 billion people. He wanted to get rid of all the overpopulation so he had a plan. Xemu took over complete control with the help of renegades to defeat the good people and the Loyal Officers. Then with the help of psychiatrists he called in billions of people for income tax inspections where they were instead given injections of alcohol and glycol mixed to paralyse them. see scientology
