text: The Big Bang theory makes quantitative predictions that can be verified. So do other theories like the now abandoned, Steady State theory. These predictions can be experimentally verified and the results used to kill a theory that made the wrong predictions.\n\nThere are currently no other theories that have such overwhelming supporting evidence as the Big Bang Theory. That doesn´t mean it´s the proven truth. It only means we don´t have anything else that does as good or better.
