The kalam cosmological argument, by showing that the universe began to exist, demonstrates that the world is not a necessary being and, therefore, not self-explanatory with respect to its existence. Two philosophical arguments and two scientific confirmations are presented in support of the beginning of the universe. Since whatever begins to exist has a cause, there must exist a transcendent cause of the universe.
