If you're saying that DNA is too complex to have evolved on earth, where else would it evolve? Panspermia just puts the origin of life in another location in the universe. It doesn't answer any questions about how that complexity would evolve.

Consider the design of processor architectures and operating systems, similar design goals but typically one cant run code from the other.
