I am an agnostic atheist. I am close to finishing my college degree in IT and I have fairly extensive understanding in most of the relevant fields of science. However, I recognize that atheists lack a burden of proof, that my position is entirely justified based on the absence of sufficient evidence for gods. I remain agnostic, depending on how one defines 'knowledge.' If absolute certainty is not necessary to qualify as knowledge, then I am a gnostic atheist. If someone were to assert that absolute certainty is not only obtainable (which I reject), but is necessary to state that someone 'knows' a fact, then I am an agnostic under that definition.
