The play ran in NYC in 2018. From the review of the NY performance in the NYT. The play within the play is called "Noah's Ark." In that play, the actor playing God is "a mellifluous blowhard named Larking" who is doubting God's existence because of the Black Plague. The troupe encounters problems filling the roles as actors die.
In a moment of stubborn curiosity that alters the aesthetic history of mankind, [the actress playing Mrs. Noah] asks what would happen if Mrs. Noah just didn’t feel like getting on that ark one day.
What would happen, [the playwright, Jordan Harrison] suggests, is the Renaissance, or very nearly. The beginning of self-consciousness, he argues, is the beginning of enlightenment. If this sounds a bit heady for a rollicking tragicomedy in which pratfalls and death throes are tumbled together, that is part of the play’s unusual scheme....
[I]t really is a thrilling, expansive, world-changing moment in a very sneaky play when [the character playing Mrs. Noah] first asks, What’s my motivation? Which is a question you can only begin to contemplate after asking, What is God’s?
