My theory is the God Incorporated Theory.
God™ is actually a multi-billionaire after-life company with over 7 billion employees and counting. Each employee controls different humanoids who live in different time zones and these employees make the decisions on how you live your life. They control you. If the employee is high up in the company, they'll likely invest well into the human and make them live successfully and prosperously in hopes of praise. However if the employee is an amateur, they will probably make the human kill themselves or become homeless or something. Every time a human being lives their life successfully from birth until death, the employee is given a raise or a promotion. This means the employee is allowed to control more important human beings, like the Pope. The employee of the year has been Jesus for the past 460 years. Every time you thank God™, you're actually thanking Sanjeet who works with humanoid customer services.
