In "Oryx and Crake," Crake presents the idea that immortality is fundamentally a concept tied to human perception of mortality. Rather than viewing death simply as an end, he suggests that mortality encompasses the awareness and fear of death that accompanies it. By rethinking the nature of life and death, Crake implies that living without the fear of mortality leads to a sense of immortality.

He likens the innocent state of babies to this notion of immortality, as they exist without the burden of understanding death. By eliminating the associated fears, Crake asserts that one could achieve a state similar to immortality, free from the anxieties that come with the awareness of life's temporary nature.
