i feel like people are confusing definitions here. "athiest" and "agnostic" are terms easily thrown around and often lumped together. they are actually 2 separate things
‘Theism’ and ‘atheism’ are about belief. ‘Gnosticism’ and ‘agnosticism’ are about knowledge.
personally i prefer this definition of "agnostic" and why i consider myself to the a part of this category: Some philosophers use the word ‘agnostic’ to refer to someone who thinks we can’t
know whether or not gods exist.
