The Kalam Cosmological argument.

[Angrboda]

So you're saying that DNA resembles a man-made creation.  Which one?

Signature in the Cell would answer that question, Angrboda. Wiki: "Signature in the Cell: DNA and the Evidence for Intelligent Design is a 2009 book about intelligent design by philosopher and intelligent design advocate Stephen C. Meyer." 

Have you read it, or do you want me to summarize the arguments? Briefly, the Genetic Code in DNA is evidence/proof of a Designing Intelligence, the same as "Welcome to Mars" leaflets, if known not to come from human beings, would be proof of Intelligent Life on Mars, because Language itself is a Code, one of the most basic forms of a Code, that conveys information. This argument, and others, are developed in depth by Dr. Meyer.

Then you should have no problem answering the question, which you didn't do. Which human-made creation resembles DNA?
