The question is: can you ever "prove" a theory. The answer is: no. Because you cannot prove theories. That's not the point with theories. A theory is the explanation that best explains all known facts. Thus, the big bang theory explains best all the facts observed around us. If we will find facts that cannot be explained by the current theory, we have to modify or even set aside the current theory.

My bf says the "BIG BANG" was when Katie Holmes got nailed the first time.

As mentioned elsewhere you technically don't prove theories. You set up a hypothesis to try and explain evidence and make testable predictions. If the hypothesis holds with the new evidence (i.e. the new evidence matches your predictions) then eventually it becomes a theory. There is some dispute in the philosophy of science as to how this works fully but that is basically it. The Big bang explained a great deal of the evidence regarding the universe and made further predictions (such as the Cosmic Microwave Background Radiation) which have been measured and so the theory holds for that instance. However theories change over time, for instance with Dark Matter and Dark Energy. So far the Big Bang fits the evidence better than any other competing theory. It is not perfect nor is it complete but is constantly being refined. There are new experiments taking place to try and answer some of the questions that the Big bang raises and to get a more complete picture of the universe.

Yes. The universe exhibits a definite temperature (about 3 degrees above absolute zero) in every direction we look. The universe is also expanding in every direction we look. If we go back in time, then the universe would have been smaller. Since the same amount of stuff exists in the universe since the time it was created (matter/energy cannot be created or destroyed), that stuff would be more pressurized and hence be warmer. Keep going back in time and the universe is much smaller and much hotter: a fireball - the remains of which can still be detected as this remnant temperature of the universe. Keep going back in time and the universe reaches a singular point of infinite density and infinite temperature. That is the Big Bang. And whilst it is indeed a theory (no-one can go back in time and actually observe the creation of the universe) there are no other ideas that come close to explaining the full picture as clearly or concisely as the Big Bang theory.
