It has always intrigued me that there should be two distinct trends in Christian attitudes towards the Big Bang theory: 1) The Big Bang theory CONFIRMS what the bible has been saying all along 2) The Big Bang theory is a SLAP in the face of Chrsitan belief. Both factions appear quite strong today. The idea that there's some central dichotomy between godless Big Bangers and god-fearing anti-Big Bangers is a myth, mostly perpetuated by the anti-Big Bang crowd. And yet even within this anti-Big Bang Christian crowd, there's still no consensus as to WHY they oppose the Big Bang theory. Some are Biblical inerrantists, arguing that the Big Bang theory flat out contradicts the Genesis story, and therefore is a heresy, others say that the Big Bang theory is an extension of Darwinism (see other answerers here) and therefore inhuman, and still others say the Big Bang theory suggests that "things sprung out of nothing and that's just logically impossible", and thus denies the very existence of God, as your question asks about. This list is hardly exhaustive. But the root cause of all of this is due to the fact that science is about having ever-changing (evolving?) views of the world and cosmos around us, because it's about learning new things through observation and deductions, while much of religion is conservative, "facts and truth" supposedly as unvarying as the medieval concept of stars in the celestial heavens. We know how just how violent and changing these stars out there, and we should be thankful to God that we happen to live in a pretty quiet stellar neighborhood.
