translation.en: Murray Gell-Mann: Well, I would guess that modern language must be older than the cave paintings and cave engravings and cave sculptures and dance steps in the soft clay in the caves in Western Europe, in the Aurignacian Period some 35,000 years ago, or earlier.
translation.zh: 穆雷盖尔：恩，我猜想现代语言一定很古老。 比洞穴壁画，洞穴雕刻和洞穴雕刻更早， 在西欧洞穴中发现的软泥上的舞步痕迹所处 的3万5千年前奥瑞纳时期以前，或者更早。
