If we look around us (and even in our own bodies), there are many structures that seem to show less-than-optimal design. What this means to some evolutionists is that this proves there is no creator. After all, a creator as intelligent as God would not have made imperfect designs.
Debunking this myth requires very little effort. First of all, how can humans judge what is optimal design? Some designs require a balance of efficiency and effectiveness, as we find in the human eye (a structure perfectly suited for human life). Also, we would hardly expect a universe that has been cursed with degeneration for over 6,000 years to maintain optimal design. The fact that we continue to survive, however, is evidence of how well the original design was. Finally, the broadening field of biomimetics (copying design from nature) shows us that God’s creation (even in its fallen state) offers a wealth of design potential—and good design at that.
