Watches don’t just magically appear out of nothing or assemble themselves without any outside assistance, therefore there must be a watchmaker doing what scientists and philosophers today call “intelligence design.”
The preceding paragraph is a modern restatement of William Paley’s Watchmaker argument for the existence of God. Just as the watch requires a watchmaker, the universe requires a creator.
Critics today argue there is a fundamental flaw in Paley’s argument. Biochemist Fazale Rana explains on Reasons to Believe:
“Despite the powerful analogy that exists between machines produced by human designers and biomolecular machines, many skeptics continue to challenge the revitalized watchmaker argument on logical grounds by arguing in the same vein as David Hume. These skeptics assert that significant and fundamental differences exist between bio-machines and human creations.
“In a recent interaction on Twitter, a skeptic raised just such an objection. Here is what he wrote: ‘Do [objects and machines designed by humans] replicate with heritable variation? Bad analogy, category mistake. Same one Paley made with his watch on the heath centuries ago.’
“In other words, biological systems replicate, whereas devices and artefacts made by human beings don’t. This difference is fundamental. Such a dissimilarity is so significant that it undermines the analogy between biological systems (in general) and bio-molecular machines (specifically) and human designs, invalidating the conclusion that life must stem from a Mind.
“This is not the first time I have encountered this objection. Still, I don’t find it compelling because it fails to take into account manmade machines that do, indeed, replicate.”
