It isn't that unlikely - at least one amino acid has been discovered in a comet in our universe, after all, so the idea that life comes from somewhere else isn't completely bonkers. (When I say "comes from somewhere else," I mean "carried on solar winds from other stars, over millennia," not "somebody brought it here.") Whether that life has DNA or something else is a matter of conjecture, of course.

them. Adversaries remain citizens of the same state, common subjects of
the same sovereign, servants of the same law."
