Modern language must be older ...

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. I can't believe they did all those things and didn't also have a modern language.

 Murray Gell-Mann
