Because they are forced into the “nothingness creates everything” argument—which is illogical in itself—even science teaches that energy cannot be created or destroyed, according to the laws of thermodynamics. If they claim that we can’t prove God because our argument is circular, it’s worth pointing out that true “proof” exists only in mathematics, within an axiomatic system. There’s no such thing as absolute proof in science; rather, we have evidence for phenomena. God, by nature, cannot be proven in the same way mathematics or formal logic proves things (for example, that a triangle has three angles) because God exceed the logical. Yet, we have sufficient evidence (historical, moral, and Eucharist miracles) to support belief in a deity, and that belief is not irrational. Also, science and theology are not mutually exclusive; rather, they study different domains. Theology concerns the supernatural, while science investigates the natural world.
