Dame Maggie Aderin-Pocock, a prominent space scientist from University College London, has declared her strong belief in the existence of alien life, predicting a definitive discovery within the next five decades. She anticipates a "positive detection" of life beyond Earth by 2075, acknowledging that such life could range from primitive organisms to technologically advanced civilizations.
Her confidence is rooted in the sheer scale of the universe, citing the hundreds of billions of galaxies and stars, each potentially hosting planets. Recent observations of exoplanet K2-18b, located 124 light-years away, have provided "tantalizing glimpses" of life, with scientists detecting molecules in its atmosphere that suggest the presence of organisms.
