No proof, we are anthropomorphic because we developed on a planet and it's conceivable others could have gone through specific physical requirements to become an intelligent race. We don't have any data on extraterrestrial life to make this claim either way.
And they can also be neither aliens nor fake, they could in fact be humans from some different lineage or time travelers from the future.
'Aliens are not anthropomorphic' is far from a scientific statement. We need more data to know how life would evolve elsewhere.

I always thought the argument that it's impossible that extraterrestrial life could be anthropomorphic to be pretty silly considering we have evidence of convergent evolution right here on Earth. If two completely unrelated species can evolved to have similar traits why would it be ridiculous to think that maybe two intelligent species wouldn't also evolve to be relatively similar? Like you said, what information does anyone have about anything that would disprove something we already, objectively, scientifically have examples of already here on Earth? I'd think there's more an argument that we'd look something similar than there is to completely debunk the entire idea. Who knows, maybe being anthropomorphic is crucial to being higher intelligence.
