Was there an ancient civilisation built on Antarctica? Well, that’s the claim made by certain posts that have been circulating online since early December 2022. Some of these posts feature photos of snow-covered, made-man monuments said to have been discovered during an expedition led by Admiral Byrd back in the mid-20th century. Turns out, these images were AI-generated. Other posts feature photos claiming to show “pyramids” in Antarctica, but they are just mountains.
