<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. In the 19th century, many people thought that the idea of God was necessary for society to function. Nietzsche disagreed with this idea. He believed that religion was a bad thing and that it should be destroyed. He argued that people needed to create their own values and that God was a relic of the past.
