1. I don't just lack a belief in God. I don't believe in the possibility of a God. Any God. The concept of a God or Gods itself is fear and superstition. I haven't just "not discovered God yet". God is not there to be discovered.
2. That means I feel free to use God as what I perceive it to be: a fictional construct.
3. That goes for all your Gods. There is no difference between your God, his God, her God, their God, and Brigid the Sun God. They're all just fictions people tell themselves to take their attention away from the eyes in the darkness outside the campfire.
Which means this is not so much a funny ha-ha comedy jokes cartoon, and more an accurate depiction of what all my religious friends think is going to happen to me after I die.
