If you have not already, please read my post "Nature vs. Scripture" before continuing.
In Part 1, I talked a little bit about how the Big Bang theory is a theory that is compatible with the Bible. In Part 2, I will tackle one of the Christian objections to the Big Bang:
Does accepting the Big Bang as fact mean that you concede any ground to evolution or naturalism? The major concern among Christians about the Big Bang is that it states that the universe is billions of years old; and these Christians believe that this is enough time for evolution to explain life naturalistically- doing away with God.
Big Bang cosmology states that the universe is approximately 13.7 billion years old. In order for naturalistic evolution to take place and end up with life as complex as it is now, it would take into the trillions of trillions of years (this calculation was performed by a naturalist, not a theist. I'll post the reference as soon as I can find it again). 13.7 billion years is way too short of time for naturalistic evolution to explain the complexity of life. This is why many naturalists do not accept the Big Bang. Many naturalists prefer the steady state or cyclic universe model (both are infinite in time). If they can have an infinite or near infinite universe, then evolution has enough time to explain the complexity of life. The Big Bang actually restricts the amount of time evolution has to produce the life forms we see today (and even the first life forms in the fossil record). Therefore, the Big Bang does not require or even imply a belief in evolution to explain life. But let me take this one step further:
The origin of life problem. Evolution does not even attempt to explain how life started; it only attempts to explain how the different types of life emerged. It assumes life already exists. There have been many naturalistic theories to explain how life began. Earth has been abandoned as a source for the origin of life (primordial soup theory). Naturalistic origin-of-life researchers have shifted their focus to extraterrestrial sources (that's why the media freaks out every time there is the slightest discovery on Mars or Titan). Dr. Michael Behe and Dr. Fazale Rana have both argued in their books (Darwin's Black Box and The Cell's Design, respectively) for the extreme complexity of even the simplest life. Dr. Hugh Ross and Dr. Fazale Rana argue in their coauthored book (Origins of Life) for the impossibility for the origin of life on earth (or anywhere else, for that matter) due to its irreduciblely complex requirements. Hugh Ross also argues against the current theory of aliens bringing life to earth in his book Lights in the Sky and Little Green Men. If you want one book that quickly gives an overview of all this material, check out Creation as Science by Hugh Ross.
For further investigation, I recommend checking out the list of resources from Part 1 and this blog post by Billy Pratt from the Ankerberg Theological Reasearch Institute:
Does 4.5 Billion Year Old Earth Prove Evolution is True?
Since the Big Bang has now been separated in our minds from Evolution, in Part 3 I will tackle the other Christian objection to the Big Bang's claim of billions of years. Does the Bible strictly teach a creation that took place in only 6 24hr days?
