Flew's reasoning is incredibly suspect, unfortunately. He looks at something as complicated as DNA and says, "Welp, I can't figure that out. There must be a god."
Flew stated in a letter to Richard Carrier:
My one and only piece of relevant evidence [for an Aristotelian God] is the apparent impossibility of providing a naturalistic theory of the origin from DNA of the first reproducing species ... [in fact] the only reason which I have for beginning to think of believing in a First Cause god is the impossibility of providing a naturalistic account of the origin of the first reproducing organisms.
So, it's highly challenging for Christians to use Flew as legitimizing
their god. Flew did no such thing. Flew specifically said, if there is a god, it is most likely the god described by Aristotle, perhaps not even a conscious god, more a "force of nature."
I dunno. I think that's a pretty good reason. I mean, DNA, reproduction, the human brain, atomic interactions
—[/size]all these things are incredibly complicated. We (humans) consider ourselves pretty smart and yet all of humanity's resources in the world could not create one butterfly. But some would have us believe that all the lifeforms and complex systems that we don't even understand formed over eons by happenstance.
But let's say the earth and all living creatures did form by happenstance. The conditions were just right on our little planet—not too hot, not too cold—and all the right chemicals came together to form life from the primordial ooze. Then our lucky streak continued, as we somehow became able to reproduce and formed into increasingly complex animal and plant lifeforms until, PRESTO, we have modern day earth! Woo hoo, we got lucky! The odds of this happening are a millionty-billionty-trillionty taken to the googleplex power. But earth was really, really lucky and everything fell into place for us. So given that, why doesn't the system break down? I mean, if all this happened due to dumb luck, there's a LOT more that can go wrong going forward than can go right.
Here's a hypothetical for what I'm talking about. Imagine that a group of students at a trade school in San Diego create a self driving car. But this trade school isn't Cal Tech, and their self driving car isn't like the sophisticated Google car. Instead, it has a random number generator controlling its speed, and an automatic coin-flipper that controls its direction. Flip-generate_num: go left at 15 mph. Flip-generate_num: turn right and go 23 mph. You get the picture. Let's call this "Lucky Car". Well it's possible that they could point Lucky Car in the right direction and it would make it all the way from San Diego to downtown Manhattan. Lucky Car made all the correct turns and driving maneuvers to traverse 3,000 of American highways and streets using its automatic coin-flipper and random number generator. It turns out that the odds of Lucky Car making it from San Diego to downtown Manhattan are a millionty-billionty-trillionty taken to the googleplex power. Coincidentally, these are the same as the odds of earth being created through happenstance. But like all truly random things, Lucky Car is a stochastic vehicle. Past results do not dictate future results. Just like happenstance earth. If Lucky Car really is driven on random operating instructions—like happenstance earth—then in the next few seconds Lucky Car will accelerate to 80 mph and run into a crowd of people waiting to cross the street at 34th and Broadway, crushing several of them against Macy's flagship store.
So the question I have for you folks who believe in happenstance earth is, why don't you rush out to 7-11 and buy a PowerBall ticket? Because on happenstance earth the odds are greater that the world will spin apart and end by tomorrow than the odds of you winning the PowerBall. And while you're at 7-11 will you please get me a kiwi-orange Slurpee? I love those things!
