The 'An Ancient Man' meme, widely known as the 'Ancient Aliens' or 'Giorgio A. Tsoukalos' meme, features the lead expert from the History Channel series 'Ancient Aliens.' Known for his expressive hand gestures and distinctive, gravity-defying hair, Tsoukalos became an internet sensation for his tendency to attribute unexplained historical phenomena to extraterrestrial influence. The meme template typically involves a scenario that defies logic or simple explanation, with the punchline inevitably being 'Aliens.' It first gained traction on 4chan and Reddit around 2010 and has since evolved into a universal shorthand for any far-fetched explanation or passionate defense of a conspiracy theory.
