- gus_massa 3y agoIt's not clear that the only option is DNA, but we will not know until we find a few independent live origins. Anyway, even if there is a unknown biology law that says that DNA and proteins are inevitable and that confuses us when we detect a second planet with life, if they have an independent origin there is absolutely no way that they have a "genetic code" that can be confusing.
