So, since I observe that this universe has specific laws and is understandable by mathematics, and since mathematics can be argued that have only meaning in relation to a mind that understands them(nobody on Earth was doing math before man; not consciously) I very logically assume that someone with a mathematical mind set those laws. You on, the other hand, assume that it's just the way it is and always was. Evidence, in that regard, points to both directions. Tell me, why am I not irrational when I see the scribble on the sand and assume someone made it, but I am irrational when I assume that the specific laws of nature of the specific universe was a result of some entity with intelligence? Explain the difference.
This is ludicrous. Mathematics does not exist in the universe. We invented mathematics. Mathematics is a description. Mathematics is our description for what we observe to be reality and what we can rationally derive.
You are trying to equate the laws of the universe to a scribble in the sand? This is a very weak argument.
Can we prove that a scribble in the sand was made by man? No.
Is it possible that a scribble in the sand was created by coincidence/accident? Yes.
So why do we assume that the scribble in the sand was created by a man? It's called inductive logic. Every (or almost every) scribble we've ever experienced was made by man. We've never witnessed a scribble that didn't seem to have a possible human source. In fact, we can scribble in the sand. It's very reasonable to assume that someone like us scribbled in the sand. It is more likely that someone like us scribbled in the sand.
Now, the laws of the universe.
Can we prove that the laws of the universe were made by someone? No.
Is it possible that the laws of the universe were created by coincidence/accident? Yes.
Here's the difference. It is not rational to assume that the laws of the universe were created by someone, because inductive logic does not lead us there. We have never witnessed anyone create a natural law. As hard as I try, I cannot change the speed of light, or make gravity work backwards, or invent some law up that I can't even imagine. We have never witnessed a god create a natural law. We don't know if it can happen, we have no evidence or reason to lead us to believe it can. I can't invent mathematical rules, or change them.
The fact that the "law" in "natural law" is the same three letters as "law" in "son in law" doesn't mean that it's the same or at all similar to one of the laws that we have written down in rule books.
Can you really not see that laws of the universe are different from a scribble in the sand? I don't care what your ultimate belief is, but I urge you to prove you're at least intellectually honest by admitting that argument doesn't hold water.
