Since drama and new comedy were played in ancient theatre’s. why did they leave out horror?

I enjoyed reading this play it has a extreme twist to it that kept it interesting . My question is exactly what does this play teach us about religious devotion, about the relationship between humans and the divine?

does the development of culture depend on the change of traditional religion?

If it weren’t for the evolution of human speech (language and writing) what other ways would humans have communicated with one another? Would a different way of speech still impact human consciousness?. Why don’t we depend on our Senses and perception the way we did in the past? also Why don’t we depend on them for survival? What caused this to happen?
