 Ultimately, Liddle argues that "which option you take, then, God or no God, is a matter of choosing something for which there is no scientific proof either way".He argues that adhering to both religious supernaturalism and scientific naturalism is not contradictory, but a "balance" of the "very essence of what it is to be human".Based on arguments for God such as the fine-tuned universe argument, and on a lack of a conclusive understanding of pre-Big Bang physics, Liddle states that "the true scientific position, of course, is that there may be a God, and there may not be a God".
