It takes only one "counterexample" to disprove the theory of an [[Old Earth]].<ref>Most of the "evidence" for an [[Old Earth]] is based on claims that lack testability, as in [[radiometric dating]], and hence would not even satisfy minimum requirements for admissibility in court.</ref> As with any logical proposition, one contradiction disproves the proposed rule. If each of 31 counterexamples has merely a 10% chance of being valid, which is certainly an underestimate, then the probability that the Earth is billions of years old is only 3.8%. With the total of these counterexamples at 31, '''they demonstrate that the Earth must be young with a likelihood of greater than 96%'''. | It takes only one "counterexample" to disprove the theory of an [[Old Earth]].<ref>Most of the "evidence" for an [[Old Earth]] is based on claims that lack testability, as in [[radiometric dating]], and hence would not even satisfy minimum requirements for admissibility in court.</ref> As with any logical proposition, one contradiction disproves the proposed rule.
