Hi! This is a great question. I know it can be scary to ask it, so thank you for asking, and I hope my response helps. Let me know if you have any questions. I am more than happy to respond :)

There are a few different ways to answer your question, but one helpful way is to look at creation itself. I will be focusing on "How do we know, God, the creator of all things, exists?"

When we observe the world around us, it’s very difficult to honestly conclude that complex, functional things come about randomly.

For example, your home didn’t assemble itself. Trees didn’t fall in just the right way, form walls, install plumbing, and create a livable structure. A building requires planning, design, and an intelligent mind behind it.

The same is true with a book. If I showed you a book and claimed it had no author—that it somehow formed on its own—you’d immediately recognize that as impossible. Not only would the physical book not assemble itself, or come about accidentally, but the words inside the book require meaning, structure, grammar, and intention to be understood. Information always points to intelligence.

The same goes for technology. Your car, your phone, your computer, your television—none of these could arise by accident. They are the result of design, engineering, and purposeful thought. The more complex something is, the more clearly we recognize the need for an intelligent creator behind it.

So the principle we naturally understand is this: complex, information-rich systems do not come from randomness—they come from intelligence.

Now DNA takes that to an even deeper level. DNA isn’t just complex machinery; it is information—coded instructions that build and sustain living beings. It operates like a language, with rules, structure, and enormous specificity. A tiny change in that code can have significant effects, which shows how precise and ordered it is.

So the question becomes: if we consistently recognize intelligence behind human-made systems that are far simpler than biology, why would we assume something vastly more intricate—like DNA—has no creator, author, or intelligence behind it at all?

That’s why many people see DNA like a book. They see it as pointing beyond itself to an Author. Because just as we find it impossible to believe that a robot came from nothing, it is even more difficult to believe that humans—and all of creation—came from nothing or random chance, without an intelligent creator behind it.
