I Could Do This All Day

Because this didn’t even take 30 minutes.

“Creationists are not against science”

Not when it suits them, no.

“Most of them use science to show that evidence points to an intelligent creator”

Via extreme cherry-picking and fallacious premises hinging on incredulity and ignorance.

“This is obvious to most people”

Well, every religion does have a creation myth. Some involve multiple deities, while others stick to one. All are very different from one another, often wholly incompatible. It’s not “obvious,” just common, and an argumentum ad populum is not compelling evidence for a designer. It once seemed obvious that the earth was a flat, unmoving disc with two spinning orbs of light going to and fro. Now, of course, we know we’re not flat, one of those orbs doesn’t produce its own light (instead reflecting the light of the other one whenever it’s not in our shadow), they’re both millions of miles away, and we actually orbit one of them instead of us being the center. Of course, that’s just one example of something we all used to believe but don’t anymore because we learned there was more to reality than simply what comfort fantasies about it we wanted to be true.

“but some like to believe against all odds that somehow it is “scientific” to suppose that all life came from a single living cell”

Ah, the common ground fallacy. It’s scientific to make no assumptions one way or the other unless the facts and evidence supports it. Just as there’s no evidence that proves the God of the Judeo-Christian religion as the architect of our existence while simultaneously disproving Prometheus being the one who sculpted man from clay and breathing life into it, there’s no evidence to empirically prove that all life came from a single living cell. However, with the current evidence we have, there’s more to support this theory than to definitively settle on one particular creation myth as anything but mythical.

“that somehow appeared out of nowhere-”

Primary mover problem. Your argument is invalid. If God can somehow simply be, not appearing from nowhere, why not the universe? If God does have a beginning, then what preceded that beginning? It doesn’t solve the origin paradox to simply apply a sapience to it. As for that single cell appearing out of nowhere, that’s not what any scientist worth his salt would claim. Abiogenesis is not an ex nihilo process. Remember, while everything we would consider alive is organic, not everything organic is alive. Your very DNA is made up of complex macromolecules, themselves little more than arrangements of various inorganic elements, including Carbon, Hydrogen, Nitrogen, and a few others.

“and by a miraculous series of billions of surprisingly beneficial mutations”

You know that more species go extinct than persist, right? Remember what I said about cherry-picking? There’s no shortage of examples in the fossil record of mutations that led to dead ends in many species’ developments. There’s also environmental factors that lead to extinction events, and mutations don’t occur overnight, much less one or two generations.

“in incredibly coordinated sequences”

Chemical reactions aren’t magic. Saying two hydrogen atoms and one oxygen atom forming a water molecule is an incredibly coordinated sequence is like saying dropping a stone and watching it hit the ground is akin to witnessing a man walking on water or raising the dead. There’s nothing miraculous about the chemical bonds formed by certain elements. Plenty of other elements form no such bonds, but that doesn’t make those elements that do “special” or “mystical.” You’re making an argument from incredulity, dismissing a wide range of information to create a narrative of design rather than natural processes of emergence.

“evolved into all the complicated life on earth”

Just because something looks complicated and designed doesn’t mean that it is. This is why the fine-tuning argument does more to disprove a designer than prove one. If it’s such an incredibly coordinated sequence or miraculous series, why are there so many examples of it not working out at all? How many stars are there in the universe? How many of them have planets? How many of those planets are like ours? If the answer to any of these questions is anything except “All of them.” then it’s not a miracle and it’s not a design. If it’s a design, it’s deeply flawed and a colossal waste of space. Throw enough pasta at the wall and something will eventually stick. It doesn’t mean you’re a master chef, just that you’ve ignored all your failures to boost your ego.

We weren’t designed. We emerged.
