In "Oryx and Crake," Margaret Atwood reflects on the hidden nature of significant life events that often occur out of view. Birth and death are pivotal moments that shape human existence, yet they frequently happen without people witnessing them. This speaks to the unpredictable and often unnoticed aspects of life that can have profound impacts on the world around us.

The idea extends to the intimate and fleeting experiences, such as sex, which can also occur in obscurity. Atwood suggests that many crucial parts of the human experience are shrouded in temporary oblivion, highlighting a contrast between the visible and invisible elements of existence. This notion prompts readers to consider how much of life unfolds beyond our direct observation.
