I'm not going to debate this topic here, but for what it's worth you're coming across as somebody who has chosen their stance and is cherry-picking their evidence and anecdotes to suit their biases.
While I agree with your suspicion that a lot of animals are more intelligent than most give them credit for, you're not arguing for that viewpoint well. You might want to revisit how you make your points.

I’ve never seen a definition of language in a scientific context that frames it in any other context other than something humans do. Please feel free to show me otherwise. Whether or not you are convinced isn’t really my concern - this is a well known scientific thing.

For such a "well known scientific thing" I certainly haven't heard of it nor can find any evidence of your claim. Yes, most papers use communication instead of language, but that's because until more recently there has been little evidence that shows any other species communications have sufficient complexity to be called a "language." E.g. having words and sentences rather than signals with a given meaning.
There is even a scientist claiming mushrooms have language https://royalsocietypublishing.org/doi/pdf/10.1098/rsos.2119... !
The closest we currently have to evidence of non-human language use I know of, comes from attempts to teach language to apes, (which is an example of some scientists saying "$organism is doing language", which you claim never happened) The general criticism was that the great apes did fairly well learning semantics but show limited to no syntactic ability.
We do see semantic capabilities in other species and there's long been reason to suspect semantic content in whale songs. Deciphering the Alphabet of whale songs is a great step towards figuring out the semantic structure. When we do, I wouldn't be surprised if we find syntactic structures as well. Until then, calling whale song language is speculation.
Do you have specific examples of places where we have both syntax and semanti
