If this analogy were to work, something would have to play the role of natural selection.
I'd like to also point out obvious errors in your statements on DNA. It has been shown time and time again that our DNA is far from efficiently encoded. It has also been shown that our DNA is quite similar to that of many other animals. It has been shown that DNA modification in chicken eggs can cause the appearance of 'dinosaur like' qualities in the resulting fetus (such as scales and teeth). It has been shown that vertabrate fetuses have their information drawn from the same region of DNA during growth (always), no matter the vertebrate animal.
These are all evidence FOR common ancestry. Coupled with the fossil record which clearly shows a trail of common ancestry and change, the case for evolution is RIDICULOUSLY STRONG.
Your hand waving claim that there is no evidence merely means you are not a scientist, don't truly understand science and don't know (or want to know) the mountain of research which supports evolution.
