Thanks, atleast you aren't ignoring the evidence that life evolved.

That's where gene-duplications, mutations and geneshuffling enters the picture.

Yes, a human being and any given organism will develop from it's DNA.
But CharlieM, the evidence is that gene duplication events, in combination with geneshufflings and random mutations acting on these, are what produce novel lifeforms. It's a matter of putting 2 and 2 together.
We have the evidence that life changed and evolved over hundres of millions of years. You don't deny this.
And we have a mechanism, oberved to produce novel information in the laboratory : Duplication of genes, mutations on duplicated genes and finally gene-shufflings, alltogether, produce new functional protein machinery.
We obser natural selection both in the wild and in the laboratory.
DNA builds organisms, genetic mechanisms change the DNA, natural selection filters the results. The big picture works and I don't see why you would deny it.
