Still viruses are very specifically adapted to life on earth, everything contains DNA and RNA. Maybe this is the only form of life that is chemically possible,

  If you define 'life' as "any process that sits at the boundary between low to high entropy to make more of itself, and is subject to natural selection and evolution to produce diversity" then I'm sure there's all sorts of things that can be described that way. Maybe even things as "mundane" as the cloud patterns of Jupiter, or some internal processes inside a star? And would we even recognize these things if we saw them, most of the time? ... But the kind of thing people mean by "life" colloquially is really multicellular or at least eukaryotic life, which only arose on earth like 600 million years ago, which is only like 15% of the time that life in the more strict sense (bacteria/archae) has existed here.
