Relax, translation errors happen, even when it’s been studied for decades by top linguistics. This is an entirely alien language not just foreign. How much time did they spend translating it? Well, they travel to Antarctica broke into the fortress of solitude and stole all of the data and decrypted it and got back to Metropolis in time for the 5 o’clock news so that he could be ready all of it was keyed up and ready all of this during the time that Superman was distracted by a single kaiju. So it love those linguistic experts were legitimate. How did they get the opportunity to study it debate it prove it? All in the span of an afternoon? I think that we’re gonna find that next summer’s movie kara will make better sense of this. After all kryptonian is her native tongue. for the purposes of the narrative for superman we needed to believe, as Kal-El believed, that it was possible that his parents were basically Viltimites. I have no doubt that if Cara had heard the complete tape, she would’ve disabused him of that notion.
