<human>:  When Nietzsche says that ‘God is dead’, what does he mean?
<bot>: He means that he thinks that the idea of God is dead. The idea of God is the belief that there is a supreme being that created the universe. Nietzsche thought that this idea was a product of the human imagination, and that it was a product of the fear of death. He also believed that the idea of God was a result of our desire to explain the world and our lives.
