From the Complete Bible Answer Book
The Big Bang postulates that billions of years ago the universe began as an infinitely dense point called a singularity and has been expanding ever since. Though the Big Bang is not taught in the Bible, the theory does lend scientific support to the scriptural teaching that God created the universe ex nihilo (out of nothing).
First, like the Bible, the Big Bang postulates that the universe had a beginning. As such, it stands in stark opposition to the scientifically silly suggestion that the universe eternally existed, not to the biblical account of origins.
Furthermore, if the universe had a beginning, it had to have a cause. Indeed, according to empirical science, whatever begins to exist must have a cause equal to or greater than itself. Thus, the Big Bang flies in the face of the philosophically preposterous proposition that the universe sprang from nothing apart from an uncaused First Cause.
Finally, though evolutionists hold to Big Bang cosmology, the Big Bang itself does not entail biological evolution. In other words, the Big Bang theory answers questions concerning the origin of the space–time universe, as opposed to questions concerning the origin of biological life on earth.
While we must not stake our faith on Big Bang cosmology, we can be absolutely confident that as human understanding of the universe progresses it will ultimately point to the One who spoke before the universe lept into existence.
