Cuneiform Video: Origins of human language — E8 Intelligence Research

We need to answer: write a focused 300-500 word discovery about the tablet discussed in a YouTube video titled "Origins of human language". We need to be specific about mathematical/astronomical knowledge, numbers, ratios, base-60 calculations, museum numbers if identifiable, and any link to sacred geometry (phi, sqrt2, pi). If the video's tablet cannot be identified, say so plainly. We don't have the video. We must consider that the video "Origins of human language" might discuss a clay tablet related to early language, maybe the "Kish tablet" or "Uruk IV tablet"? Or maybe it's about the "Proto-cuneiform tablet from Uruk (c. 3400-3000 BCE)" that shows early accounting. Or perhaps the video references the "Plimpton 322" tablet, which is about Pythagorean triples, but that is about mathematics not language. However the video title "Origins of human language" might discuss the "Uruk tablet" with early signs, but also maybe the "YBC 7289" tablet showing sqrt(2) approximation.
