No human designed DNA. Your point is not well taken. You seem to neither understand the ID nonsense nor the science.
It's called "selection". If I want big red dogs, I select for the biggest and reddest puppies. You do that several generations and you'll get big red dogs.
Eventually we are going to be able to create a gene that gives us big red dogs starting off with rabbits or chipmunks. It really won't matter.
