Mexican Congress held a second session on UFOs featuring 3-fingered Peruvian mummies believed to have been found near Peru's ancient Nazca lines. Mexican journalist Jaime Maussan presented mummified remains at Congressional sessions, claiming they were unlike any life on Earth. While scientists confirmed they were once living organisms, they did not declare them extraterrestrial. The sessions featured various presentations both supporting authentication of the mummies and speculating on their potential non-human origins, while critics have dismissed such evidence as stunts debunked by science.
