Letter from God to Man

"This poem isn't actually about religion. It is kind of irrelevant to the piece whether or not you believe in God or a God or anything like that. Thats not the point......"

Is this really not about religion? Y12 suggested this linked very well to some of philosophical debates about the existence of God and the responsibility that man has in our world. Does it suggest that everything that happens is due to the free will of man give by God? What involvement does God have in creation?
