The Search for Extraterrestrial Intelligence: A Historical Journey traces humanity’s oldest question across centuries of dreaming, discovery, and scientific determination: Are we alone in the universe? From ancient myth-makers who imagined visitors descending from the heavens, to modern scientists armed with powerful telescopes and AI-driven data pipelines, this audiobook follows the full arc of our quest to find other intelligent life.

The journey begins long before radio dishes and spacecraft existed. Humanity’s earliest civilisations looked up at the stars and felt an instinctive pull toward the unknown. Ancient philosophers wondered whether the stars were suns like our own and whether other worlds might hold life. Medieval scholars quietly debated the plurality of worlds. This deep-rooted curiosity—part fear, part longing—laid the groundwork for today’s scientific search.

Across ten richly detailed chapters, the audiobook explores how that timeless wonder evolved into a rigorous, data-driven global effort. We enter the dawn of modern SETI with Project Ozma, Frank Drake’s pioneering 1960 attempt to tune in to whispers from nearby stars. We follow the development of the Drake Equation, which transformed a philosophical question into a structured scientific framework. We cross geopolitical borders to examine how Soviet astronomers contributed bold theories and early radio searches during the Cold War.
