You have claimed that DNA is evidence for divine intervention in the universe. On top of that you have claimed that God must be a first cause. (I will assume for brevity, that you mean God was the direct cause of the Big Bang. Honestly, Aristotle knew not an iota of our modern understanding of the cosmos.)But religion does not accept a God based on NO EVIDENCE whatsoever! There are many evidence. From the subtle parameterization of the cosmos for it to be able to sustain life, to the complicated designs which sustain life, from the DNA that encodes information that I dare you to create via random "noise"-making processes, to the very things you feel and which undermine every materialistic shallow explanation of the world. Not to mention the logical proofs of Godel and Aristotle for a First Cause. Would you call that "blind faith"? No...
Now let's do a little exercise I like to called Reductio ad Absurdum. In Reductio, you go ahead and pretend like the premises are completely true, then you derive consequences that are absurd. This tells you that the original premises stink, and should be thrown out the window.
Okay, let's do this. Let's pretend like God actually caused the big bang, and that God directly interfered with the Earth in order to design DNA. Those are the premises. Now let's draw some conclusions.
God did the Big Bang directly. When he was finished, he left the universe alone and did not touch it. The universe went about forming stars and galaxies by completely natural forces. It later formed the solar system and earth by completely natural processes. DNA molecules are composed of atoms, mostly carbon, oxygen, hydrogen, and phosphorous. These elements were all formed completely naturally (no God involved) in the explosions of stars during their supernovas. DNA chains are made of nucleotide bases. These bases can form naturally and Miller and Urey showed how that can happen, sans God.
So God did the Big Bang, then he departed the universe and went on vacation for 9.7 billion years. The universe did everything naturally by itself while he was gone. Then suddenly, at around 3.5 billion years ago, God comes back to the universe and finds this one little planet near a star in the Milky Way and he says to himself : "Golly gee wizz boss -- I think imma design me some DNA today!"
So God did not create DNA... he sort of fashioned it like a chef from existing ingredients found directly on the Earth already. Yeah that's right. The necessary ingredients were already sitting right there on Earth, ready for God to come along and start stitching them together.(what a coinq-ee-dink!).
What was the first thing God made? God made a bunch of bacteria to slosh around the ocean. And then he took his spanking-new Divinely-Fashioned DNA Molecules and placed most of them where? Yeah, I'm asking you. Where did God put most of the DNA on this planet? Do you know the answer to that question? (Have ever even considered asking it?)
Welp, God put most of his Special Divine DNA in microscopic little bags with needles on them that slosh around in the ocean infecting various bacteria that they ram into (by accident). Those things are called Marine Bacteriophages. They are the most common DNA container on the face of planet earth - by far - by far!
So basically God did the Big Bang, went on vacation for 9 billion years, then came back and decided to cover the entire face of some little rocky planet with viruses that squirt DNA into bacteria. Oh, and by the way, he specifically designed these things to-order, according to his genius plan.
So skakos, we have completed our little Reductio exercise, and we have landed on an absurdum. At this point you have two choices. 1. You can try to amend or discard your premises. or 2. You can continue to make yourself look completely idiotic. Your choice. Ball's in your court, buddy.
