Given that most religions give explanations for what happens to humans after death, and there is no strong evidence for anything happening to humans after death, is it fair to say there is no strong evidence that everyone in the world should join a particular religion if there are no state-mandated benefits for being in that religion?
Note: in some countries there are benefits for being in a particular religion, like eligibility to become head of state or head of government, but "state-mandated" sounds better than "government-mandated" because some people view the government as a separate entity that does not always act according to the wishes of the people and the state as a more permanent and inclusive entity.
