Actually, your premise is incorrect at its core; a theory is very, very far from a guess. More correctly, a theory is a working analytic model, a fact-based framework for the description of the observed and confirmed existence of and interaction among a set of phenomena. A theory is developed through, supported by, and adjusted, if and as necessary, in accordance with both observational and experimental evidence. A theory must be objective, logical, consistent with all observation, be not inconsistent with known established, principles, and be testable in that when applied to a set of observations pertaining to the subject of the theory at discussion the conclusion derived thereby be consistent both with the theory and with confirmed observation.
By its very nature, the matter of the existence or non-existence of the supernatural is inconsistent with theoretical analysis; whether or not there be a god, gods, or anything of the like, perforce is a matter purely of conjecture and speculation, an intellectual excersize incapable of rising to the level of theory, mere guesswork.
