Here's why Creatards might be right

[TheRocketSurgeon]

Logic doesn't work like that. The appearance of design, simply because you know that humans make complex things by design, does not mean it must be design when you find it in nature. I've tried explaining the difference (going "against" natural ways of things, like heating the ore in a crucible until it is the pure metal), but you keep saying "humans make stuff, so every stuff is made".

Post hoc ergo propter hoc. "It came after, therefore it was caused by." It is a common fallacy, because of our human pattern-seeking brains. An example is that you see a lightning flash, way off in the distance. A few seconds later, you hear a gigantic BOOM! Was the boom the thunder from that lightning? You might assume so. But what if you find out later that the lightning was several miles away from you, too many miles away to be able to hear the thunder from it, but the lightning actually hit a gunpowder factory and exploded it, resulting in a bigger boom, loud enough for you to hear at that distance? Your experience taught you it must be thunder, but the facts, upon closer examination, did not bear that fact out.

Your experience tells you that everything that is complex must be designed, because you have only ever seen complex things by design. Okay. We get that. But that's not the only way complexity can emerge. We're telling you the factory explosion is what caused the sound you heard, and all you're doing is sitting here saying, "Nope! Thunder always follows lightning!!"

And we're sitting here, telling you that's not how it works, and yet you keep repeating the same fallacy over and over again.

There may in fact be a designer behind the universe. But it's not necessary as an explanation. It is not required to explain it, so you'd need a good reason to add that to the explanation, and there's no good reason.

You trying to apply this principle you see in the world around you, but that doesn't mean it's applicable to scientific explanations. You've never seen four hydrogen isotopes squeezed together to form a helium nucleus (or any other type of fusion) in all your experiences of life, so it's counterintuitive to think that enough gravity could squeeze gasses together until they become other gasses and release energy, but that doesn't mean the sun doesn't operate by nuclear fusion.

It's the same argument we get from Creationists: "I've never seen anything evolve! Cats give birth only to cats!", as if the only way they can grasp how evolution works is to see a cat give birth to a puppy (which isn't even what it says).
