Creation is not a scientific theory. There are no falsifiable hypotheses possible when dealing with a supernatural matter. One cannot test whether god created the universe or not, if nothing can be traced directly to the hand of god... which would require that we can physically see the hand of god and link it to whatever one religion, out of hundreds, claims to have been created by him. The "Big Bang" theory, like any other scientific theory, is comprised of hypotheses that are tested and based on observable evidence... there is some evidence of the occurrence of the Big Bang... background radiation, for example. The half-life of radioactive isotopes, such as cesium, is far more accurate and reliable than the most expensive mechanical watch in the world... much less a testimony written 2000 years ago, or fifteen minutes ago for that matter, for which no evidence has been gathered since.
