Agnosticism is a question of knowledge, atheism is a question of belief. Knowledge and belief are two separate things.
Technically a agnostic is someone who states they do not know a god or gods exist. If they believed any god had met their burden of proof, they would no longer be an agnostic. As a result, agnostics are technically atheist as well.
