The point was that evolution is based solely on mass and energy. Information is not even factored into the equation. However, information cannot come from just a big bang. This is not evident in our world. So the point is that there is a "non-material" element to information. The question then is "Where did information come from?" Our DNA has very complex information encoded in it. That shows a supremely intelligent entity put the code there. It would be like having a computer with an highly complex design in the software yet we just all think "Wow. It is great how that software just evolved from nowhere." Why is that not possible? Software on a computer is much less complex than our DNA.
Patterns occur naturally - no help required from a 'designer'. Many patterns occur in nature without the help of a designer snowflakes, tornados, hurricanes, sand dunes, stalactites, rivers and ocean waves...
DNA is a molecule with certain chemical properties that causes it to build proteins. It is no more special or magical than any other molecule.
Simply by natural selection patters that reproduce often are more successful in well, reproducing. Over time this become more complex representing something similar to a "code".
The analogy with the computer does (as said before) not work here as we did not start by having a full build computer with no software and nobody is claiming that.
Edit: To late, but wow! also works on your next argument.
