We so often, as free-thinkers, get embroiled in arguments concerning fine-tuning or evolution. Proponents of such arguments invariably claim that something or other is too complex to be explained by natural means. Therefore God. We often pick holes in such claims to the probability of these things, and frequency of the event in question.
However, in this short post, I would like to take a different tack. How do we know that something really is very complex?
As it stands, the human brain is the most complex thing in the known universe. But, on the scale of complexity, is this truly “too” or “really” or “overly” complex in terms of natural mechanisms? Because, as when thinking of infinity, whenever we consider something complex, we can merely imagine something twice as complex.
If, as the most complex thinker in the known universe, we had a brain that was twice as complex, or half as complex (but whilst retaining the ability to have this conversation!), theists would still be saying the same thing, In other words, the intrinsic complexity is rather meaningless. It’s about the relative understanding of the level of complexity. But, even then, we are benchmarking on things that our brains can conceive. This says nothing of the “objective” standing of complexity of that which is being evaluated.
I’m sure I could write more on this and present it more formally but you get the point. When a theist next argues that X is too complex to be explained by Y, just question on what spectrum of complexity they are basing this. How do they know that X sits in any given position on that spectrum?
