The alleged bodies of two “non-human” beings were presented during a congressional hearing in Mexico, generating a mixture of surprise, disbelief and ridicule on social media on Wednesday.

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.
It is pretty arrogant to assume every possible intelligent lifeform is a) carbon based, and b) looks like a mutated human, meaning appendages, face, head, all in the same relative positions. Sorry, I still believe that the reason we haven’t ‘discovered’ alien life, is because we don’t know what we’re looking for!
Absolutely on your last point, life elsewhere will have many environmental pressures that force things into a different direction. There will also be some things that work the same (convergent evolution). I used to think similarly about carbon with the idea that silicon or others could work as a base (and it may still happen) but I’ve seen a few good debunkings that knocked down the probability of it. Carbon is just so good chemically at what’s needed for complexity.
