Anyone who says that there was nothing before is spouting nonsense. Any honest scientist will tell you that we don't know what happened at the Big Bag, much less before it. The math of the strong, weak, and electromagnetic forces workout to a unified path as you reach Big Bang energies, but except for a split second after the event. That's because gravity has to be accounted for and we have zero idea what gravity is. Worse, we have two theories: one that says that gravity is transmitted by a particle (that we can never hope to test ) and one that says that it bends spacetime (that has no mechanism in the Standard Model). Until this is resolved, you can't make any statement about at or before the Big Bang. On a side note: quantum physics seems to suggest that the universe abhors the idea of nothingness. Emptiness has a vacuum energy that generates particles from "nothing." It seems happy to let "something" happen as long as it happens in a way conserving opposite effects (spin, charge, etc). One idea is that a mirror anti-matter Big Bang "exploded in the opposite direction," which is the balance to this one. But, it will all be speculation until we can explain the Big Bang's behavior, itself.
