Abstract
One cannot dismiss the Big Bang as "just a theory." Various lines of evidence confirm the "hot Big Bang" as the best model for the origin of the universe. The most widely known piece of evidence is Hubble's Law (galaxy redshifts), but the universal abundances of light elements and the cosmic microwave background radiation add convincing support to the hot Big Bang model. This paper discusses these three lines of evidence with emphasis on the last two. Theological implications of the Big Bang are also discussed. Among ancient Near Eastern cosmologies, only the Bible presents the universe as having a beginning ex nihilo. Two historic alternatives to the Big Bang that avoid a beginning are presented and rejected. Finally, Gentry and Humphreys have proposed young-earth creationist models contrary to the Big Bang. We find their galactocentric cosmologies fail scientific and theological scrutiny.
