In the novel "Ender's Game" by Orson Scott Card, the characters face a grim reality about humanity's place in the universe. The idea presented is that while the world could ultimately thrive without humans, it is humanity's instinct to survive that drives the plot. The significance of human existence is highlighted, as it is more about the preservation of the species rather than the fate of the planet itself. This reflects a deeper concern for the human condition and our impact on the Earth.

The quote emphasizes the inherent value of human life and the continuous struggle for survival. It suggests that despite the potential for the planet to evolve without us, humans have a innate drive to continue fighting for their existence. This tension between individual human concerns and the larger ecological narrative raises questions about responsibility, survival, and the legacy we leave behind, underscoring the importance of understanding our role in the world.
