Atheism is described as a doctrine that holds what fundamental belief?

Atheism is fundamentally defined by the belief that no divine beings exist. This stance rejects the existence of any god or gods, asserting that there is no supernatural power or deity governing the universe or influencing human affairs. This belief can be based on various philosophical arguments, scientific reasoning, or a lack of empirical evidence supporting the existence of the divine.

The other choices do not align with the core tenets of atheism. The idea of multiple gods pertains to polytheism, while the belief in a single divine being corresponds to monotheism. Claiming that all religions share a common truth suggests a belief in some form of divine or spiritual reality, which contradicts atheism's fundamental assertion of the non-existence of divine beings.
