Prove it. Things like "complex" have rigorous specifications, and you should be able to prove the relative complexity without resorting to handwaving. You've already made an assertion, apparently by reason of incredulity, so throw us some red meat.
haven't you read some of the details of our amazing dna code? It's not handwaving at all...there is a specific numbering system in our dna code and of course it puts into motion all of the complex functions of our bodies. I can do some reading up and send you some links if you like but I'm suprised you haven't read a bit about it.
