About this video
We Almost Didn’t Exist! Understanding Life Across Different Worlds | Space Documentary
In this special compilation space documentary, we explore how fragile and how rare a living world truly is. From Proxima Centauri b, the closest Earth-like exoplanet that challenges our ability to survive beyond the Solar System, to Earth’s own 4.54-billion-year journey from a hostile molten world into a living planet, each story reveals the fine balance required for life. We then push that balance to the extreme by imagining what would happen if Earth’s Moon were replaced, exposing how easily our climate, oceans, and stability could collapse. Together, this space documentary connects survival, evolution, and cosmic chance, asking a single question: why does Earth still work when so many worlds fail? Join this space documentary to test the limits of life itself.
