UFOlogy is the study of unidentified flying objects, often focusing on sightings and encounters that cannot be easily explained. Researchers in this field analyze reports, photographs, and videos to determine whether these objects could be extraterrestrial spacecraft or other phenomena. The field has gained popularity since the mid-20th century, particularly after events like the Roswell Incident in 1947. UFOlogists often investigate government documents, witness testimonies, and scientific data to uncover the truth behind these mysterious sightings and their implications for humanity.
