Science, unlike philosophy and metaphysics, cannot deductively prove a creation or God. Science is an empirical and inductive discipline, meaning that it cannot be certain that it has considered all possible data that would be relevant to a complete explanation of particular physical phenomena or the universe itself. Nevertheless, it is reasonable and responsible to attribute qualified truth value to long-standing, rigorously established theories until such time as new data requires them to be changed. This is what enables science to 1) identify, aggregate, and synthesize evidence indicating the finitude of past time in the universe and 2) to identify the exceedingly high improbability of the random occurrence of conditions necessary to sustain life in the universe."
