Abstract
This chapter starts with a definition of theism, and distinguishes two ways in which empirical evidence might be relevant to its truth. Seven evidential objections to theism are spelled out. They rely on many different empirical facts, such as so‐called divine hiddenness, features of our universe, biological evolution, the occurrence of gratuitous natural evil, and the elimination of religious explanations during scientific progress. Finally, it is argued that a purely secular explanation of all religious beliefs in human cultures is vastly superior to religious accounts.
