I did not read the entire thread, but based on the book "A Brief History of Time" I have found reason to believe in the Big Bang Theory, just not in the atheistic sense. I do believe the universe is infinite... I guess. I also believe it is expanding, as physics has shown. If it was not moving outward, it would have to be infinite, static and motionless to keep it from collapsing on itself at an accelerating rate. It is not motionless, so therefore the gravity would be imbalanced... yada, yada, yada.
As many have said, the BB Theory started out as a Christian defense. The Holy Spirit and the Word of God created the energy that set thing sin motion. God created Creation, but the motion of the Universe suggests that all things were sent out from one place. There is no reason to throw out the baby with the bath water.
The same way modern science does not have to be at war with God, the Big Bang Theory does not have to exclude God.
