Which ancient country invented theatre?

Had you a Time Machine with translator, you’d hit it off with “ancient” Greek civilization. But try that with present-day Greece. Their spread to present day culture is minimal. 1960 Never On Sunday 1964 Zorba the Greek 1970 Z. Now THAT’S a Greek Tragedy.

I've not been to ancient Greece

I think that both Japan and Chinese had theatre May even before Greece.
