Throughout this play, there is a common theme of humanity’s relationship with God. In the beginning of the play, the Domin explains why robots were created. While there were financial incentives later, the first robots were created to replace God. As Domin states:
He wanted to become a sort of scientific substitute for God. He was a fearful materialist, and that’s why he did it all. His sole purpose was nothing more nor less than to prove that God was no longer necessary.
Ultimately, if humans are able to create new life in their own image, then they become the new God. In the beginning, the robots appear and talk like humans, but they lack the ability to understand death and empathy. However, the robots begin attacking in Act II, causing the scientist to call upon their own creator again. One scientist prayed:
Oh, Lord, I thank thee for having given me toil. Enlighten Domin and all those who are astray; destroy their work, and aid mankind to return to their labors; let them not suffer harm in soul or body; deliver us from the Robots and protect Helena, Amen.
It is at this moment that the humans finally understand what it is like to be God because their creation is now fully humanized and a reflection of themselves. Similarly, the robots go back to the humans and ask them to help them because they are unable to create new robots. As we examine the relationship between humans and robots, we are able to see the relationship between God and humans. While the humans are scared of their creation and aren’t pleased with them, the scientists still admire their creation. Likewise, this play is a testament showing that perhaps God is afraid of our destruction as well despite being still proud of our abilities.
