Michael, if I tell you we still don't know, do you absolutely promise not to say that it didn't happen, then? We are within billionths of a second of the event out of over 13 billion years. We may get there, we may not, but at least science is honest enough to admit that we're not quite there. The steady state theory is adhered to these days only by the ornery, and creationism not only relies on having faith instead of evidence :-) but also on denying all the evidence we do have for the Big Bang.
