So I have presented the evidence for a cosmic beginning and for cosmic fine-tuning many times to atheists, going slowly over the history of cosmology and astrobiology, pointing out the discoveries that led all the science-accepting grown-ups to accept the Big Bang cosmology and the cosmic fine-tuning.
A couple of examples of evidence for the cosmic beginning: cosmic microwave background radiation and nuclesosynthesis.
The response from atheists who listen to this evidence is usually something along the lines of “Am I going to Hell?” and “Who made God?” or “Who Designed the Designer?”
Well, I’ve answered the Am I Going To Hell response to scientific evidence for a Creator and Designer in another place. The response to the who made God question is simple: 1) scientists acknowledge the Big Bang as the beginning of all space, matter and time itself. 2) the cause of the beginning of time must exist outside of time, and the cause is therefore eternal, and CANNOT therefore come into being itself.
For an answer to the last question about the Designer, let’s turn to Jay Richards, probably my favorite Christian thinker, (tied with Stephen C. Meyer).
Watch this for two minutes:
I just want to make sure that everyone gets the two points there.
First point is obvious. When it comes to objects that have the appearance of design, we have to look at the features of the object itself. If the object exhibits hallmarks of design, e.g. – specified complexity, irreducible complexity, etc., then we have to compare the design and non-design explanations for the object and choose which is the most reasonable. We do not need to know anything about who the designer(s) are, and you can see this in other areas like SETI, where nothing at all may be known about the originator of a coded message from space, yet still naturalists can accept that a coded message was sent (e.g. – first 100 prime numbers in beats and pauses).
The second point is that atheists have to account for the fine-tuning within their worldview as well, and give an explanation that is more probable than a Designer.
Questions like “Who made God?” and “Who Designed the Designer?” are asked in order to avoid having to provide an explanation for the scientific evidence we have today. It’s not that atheists have the answer to the evidence, it’s that they want to ask silly questions in order to avoid having to comply (rationally speaking) with the scientific evidence they see with their own eyes. Today, we have the scientific evidence for a beginning of the universe, and for fine-tuning of the universe to support complex, embodied intelligent agents. So that’s why you need to focus them on the important question: what is the explanation for the scientific evidence within an atheistic framework – how do they fit the scientific evidence we have today into their worldview?
You have to watch out for their response of forced ignorance in the face of scientific evidence and demand that they deal with the scientific evidence that we have today. The more progress we have made in science in the last 50 years, the stronger the evidence for a cosmic beginning and for cosmic fine-tuning have become. This isn’t going away. Denial of today’s evidence and hoping for reversals of what we know today is not a rational response to the scientific evidence of today.
Let me give you a case in point. There was a recent debate where a prominent atheist said he was not even sure that the universe began to exist, despite the fact that this is guaranteed under the Borde-Guth-Vilenkin theorem. The BGV theorem says that any universe that is on balance expanding must have a cosmic beginning. (And our universe will be expanding outward, eternally) Atheists like to clump together on atheist podcasts, atheist blogs and atheist chat rooms where they can all agree amongst themselves that the universe didn’t have a beginning and wasn’t designed – so that they can keep living as if no one designed them for a purpose that might interfere with their desires. But this is just willful ignorance in the face of solid scientific evidence, and we need to demand that they account for the scientific evidence we have today within their worldview. We can’t allow them to continue in their Flat-Earth worldview because they just plug their ears and shut their eyes to the progress of science. Self-inflicted ignorance is not a rational response to the progress of science.
