Language is a system of grammar and syntax for converying meaning. Until you find evidence of those, calling something language is a baseless opinion. 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
