How to seed an entire galaxy with life.

We are talking about efficient seeding of the galaxy with DNA carrying microbes operating with a magnificient synthetic genetic code, we are not talking about storking primate babies. The goal would be to establish a biological substrate and atmosophere for colonization later. If higher forms developed naturally, they could be tweaked into a useful commodity. Targeting ripe planets or a shotgun approach both seem logical. According to Francis Crick, co-disoverer of the double-helix, what is NOT easy is starting life from scratch and developing multicellular organsims much less advanced civilizations. If the "Eternals," one or more civilzations up to 10 billion years old, synthesized versions of DNA and systematically spread them about the galaxy through a collection of cosmonaut microbes, we would expect the same DNA to be found in multiple life forms on multiple planets, and likely some noticeable similarities in life forms, depending on environment pressuress. The "junk" in our DNA could contain coding subject to activation through directed electromagnetic radiation, of which, DNA is proven to be sensitive. So, instead of life starting from scratch over and over on different planets, a much more rapid and uniform spread of life would occur with directed exogenesis/panspermia with colonizing armies of genetically engineered microbes. Should we do the same with selected microbes from Earth?
