The universe is a pretty big place. If it's just us, seems like an awful waste of space.

About Stephen Hawking (1942-2018)
British theoretical physicist whose Hawking radiation work and A Brief History of Time (1988) brought black-hole physics to a mass audience while he lived with ALS for 55 years. Closely associated with Roger Penrose (his collaborator on singularity theorems) and Carl Sagan (fellow popularizer who wrote Brief History's foreword). For an intellectual contrast, see William Lane Craig, American philosopher of religion — Craig's Kalam cosmological argument depends on the Big Bang requiring a divine first cause; Hawking's no-boundary proposal was specifically designed to remove the moment that would require one — the cleanest cosmology-vs-natural-theology contrast in modern thought.

Understanding this quote
What it means
Life existing only on Earth, given the staggering scale of the cosmos — hundreds of billions of galaxies, each containing hundreds of billions of stars — would be a profound cosmic inefficiency. The sheer vastness of space makes the idea of human uniqueness statistically implausible. This is a pragmatic, almost mathematical argument for extraterrestrial life grounded in probability and scale.
Relevance to Stephen Hawking
Hawking spent his career mapping the universe's deepest structures — black holes, the Big Bang, quantum gravity. His work constantly confronted cosmic scale. He publicly supported SETI and the Breakthrough Listen initiative, co-signing a $100M search for extraterrestrial intelligence in 2015. For him, the question of alien life was scientifically serious, not speculative fantasy.
The era
Hawking lived through the golden age of exoplanet discovery — the Kepler telescope launched in 2009 and identified thousands of Earth-like worlds. SETI gained mainstream scientific credibility. The Drake Equation entered public discourse. As humanity confirmed planets orbiting nearly every star, the statistical case for life elsewhere grew overwhelming, making Hawking's intuition increasingly well-supported.
