Why would detecting coded radio waves from space be considered proof for the existence of intelligence?
Watch the film Contact. The first Pulsars were thought to be exactly that sort of proof, we now know better, there are many natural processes that seem at first sight to be artificial. If DNA really did contain coded information we could see it. That is precisely why creationism is junk science, DNA sequencing reveals exactly what it should if the underlying process was random mutation combined with natural selection. Edit: Pulsars were called LGM, little green men, when originally discovered because scientists did think there was something special to be explained, we now know better. And read up about evolution, once a self replicating molecule was established evolution could and did build up all the complex structures we see today, including the cell. The only ‘accident’ needed was the accidental combination of molecules in the early earth, something that only needed to happen once.
