Scientists are exploring the possibility of alien life through the study of technosignatures, which may hold clues to the existence of extraterrestrial civilizations. Some researchers suggest that human activities, such as radar signals from airports, could potentially be detected by aliens, while others propose that certain planetary conditions, like hidden magma oceans, could support life on rocky exoplanets. There is apparent disagreement among outlets about whether evidence of alien civilizations has been found, with some reporting that most experts now believe aliens exist, while others frame the question as still unanswered.
