No, they insist, we don’t need God to explain anything; energy is self-existent, without beginning or end. But this premise violates the second law of thermodynamics, which states that energy continually entropies. Were it self-existent, without beginning, it would have been here forever and would have long since reached the state of complete entropy, which it obviously has not. Natural laws, too, they say, are self-existent. Neither lawgiver nor reason is needed. Intricate laws that govern the universe were apparently here before the universe or came into existence simultaneously with it. “This is simply the way things are,” says the atheist. but is such a claim rational?
