Clarification: Not a religious god, but the first force. Starting question: What was the original cause that started everything, how can there be an original cause without god? Response: Case A: There was no original cause; the universe always was and always will be. Result: No god. Case B: There was an original cause. Then what caused the original cause? Another cause would lead to an infinite loop and achieve nothing, so the original cause must always have existed. Why couldn't the universe have always existed, it would be illogical to think otherwise? Result: No god.
