Greek drama evolved out of religious celebrations involving goats?

Yes, Greek drama evolved out of religious festivals, specifically those honoring the god Dionysus. During these celebrations, known as Dionysia, choruses sang hymns in honor of the god. Over time, these choral performances developed into more complex dramatic presentations, incorporating characters, dialogue, and plots. Eventually, these early dramatic forms gave rise to the tragedies and comedies of the Classical Greek theater.
