Who's to say that we'll ever know what happened before the Big Bang? We're still trying to understand what happened tiny fractions of a second after the Big Bang. Speculation about what happened before the Big Bang is just that--speculation, not science. Cosmologists admit that there's simply no scientific explanation for the origin of the singularity which birthed our universe.
Your criticism makes it painfully apparent that you don't know what you're talking about. The Big Bang theory describes, literally, the evolution of matter in the universe--from a proposed singularity of infinite temperature and eventually cooling to the atomic structure of matter that we observe today. It does not attempt to explain the universe's history before this singularity.
Moreover, the fact that we cannot explain prior events (i.e., how all that energy got there in the first place) doesn't undermine the Big Bang theory, because the Big Bang wasn't proposed to explain the origins of the energy which led to the creation of the observable universe. Rather, the scope of the theory is limited to what happened after the Big Bang--to reconcile "empirical science" such as cosmic microwave background radiation, the redshifting of distant galaxies, etc. While there's a possibility for refinements to the theory as technology continues to enhance our ability to observe (e.g., the LHC, WIMP detection), there's currently tremendous evidence for the general Big Bang model. So, is the theory getting "less and less support" these days simply because you disagree with it?

If your "major's" truly in physics (as my bachelor's was) and you want to "discuss" points of view then I suggest expanding your resources to include sites like these wherein the level of discussion is more on par with your background.
Indeed, there are scientists on the ID/creation side but there is no science on the ID/creation side.
