According to the Big Bang Theory, the universe, having never before existed, suddenly appeared at the time of the Big Bang, when something exploded, and particles spread outward through space, conforming to the Laws of Physics. Now if the Laws of Physics themselves did not exist before the Big Bang, but came into being along with all matter, how can we trust the Laws of Physics to remain constant? For if the Laws of Physics were not always what they are now, there is no reason for us to be confident that they will always be. And therefore, there is no reason to believe that the universe will not suddenly vanish or change into an elephant. But if there is a Creator who established those Laws, then it makes sense that they should be constant. And it is written of Jesus Christ in the Book of Hebrews in the Bible that He is "upholding all things by the word of his power".
