Actually, when I was... "pagan", I still never believed in deities. Not sure I ever have. As a kid, I thought the world was too evil, but despite being raised Christian, I just didn't care in the least whether God was real or not. Later, I was more concerned with other things -- learning as much as possible about magicks, the proposed nature of reality, planes and s**t -- but amusingly viewed the existence of gods as a stretch. Even as thoughtforms, I just viewed them being called gods as arbitrary and figured they were pointless. And now I'm just an atheist with no supernatural beliefs who sometimes wishes magic were real.
