Or, in many different cultures, the gods, plural. Because this paper is written as part of a series of Rosh Hashanah essays, I will continue throughout to use the monotheistic preference of God, capitalised and in the singular. As the essay will explain, believe and faith in God’s existence is not the prerogative of one monotheistic group over others, nor of monotheists over polytheist perspectives. The question this paper addresses is whether some sort of Being, however defined, and named as God, a god, the god or the gods, however described, exists; and if so, how this might be ‘proved’.
