    Want to convince me? DNA samples that don’t match anything here on Earth well. Most everything on this planet, definitely the large forms, all share most of their DNA characteristics. Showing something that is even 50% different would be a falsifiable test.

    I would assume other life probably has to have something DNA-related, and chemically there are constraints that would be common, but something very different in arrangement would go a long way towards proof.

      There should be some biochemical macromolecules at the very least and likely some protein analogues. Anything like that would have chemical properties that are exceedingly simple to test and verify, and fairly simple to compare to existing proteins and macromolecules on Earth.

      Hell, an ambitious biochem undergrad could run these tests; if the biochem community didn’t sign off, I’m pretty comfortable completely dismissing these claims.
