The belief that there might be a higher power or some form of transcendent existence in the universe or multiverse, while not being certain about it, can be described as agnosticism. Agnosticism is the philosophical position that acknowledges the limitations of human knowledge and holds that certain aspects of existence, including the existence of a higher power or deity, are inherently unknowable or beyond the scope of human understanding.
Agnostics neither affirm nor deny the existence of a higher power but maintain a stance of skepticism or uncertainty. They often express doubts about the ability to gather empirical evidence or rational arguments to conclusively prove or disprove the existence of a higher power. Agnosticism can take various forms, ranging from religious agnosticism (uncertainty about the existence of God) to broader metaphysical agnosticism (uncertainty about the nature of reality itself).
It is important to note that agnosticism is distinct from atheism, which is the absence of belief in the existence of deities, and theism, which is the belief in the existence of one or more gods. Agnosticism is characterized by its emphasis on the limits of human knowledge and the recognition of uncertainty regarding matters of the divine or ultimate reality.
