AI reveals ancient symbols hidden in Peruvian desert famous for alien theories

The massive tunnel was previously hidden beneath a temple 40-feet below the ground just west of Alexandria, Egypt. Artificial intelligence has catapulted the world into the future with platforms that can simulate how humans talk and even process information -- but the tech can also help solve history's great mysteries. Researchers with Yamagata University Institute of Nasca and IBM Japan used a deep learning AI model to uncover Peruvian geoglyphs etched into the Nazca desert that date back to between 500 BC and 500 AD. Geoglyphs are depressions made to the earth to create various shapes and lines, with Peru having what are considered the world's most famous geoglyphs known as the Nazca Lines. Geoglyphs are often massive, with previously discovered Nazca Lines reaching up to 1,200 feet long, which makes them virtually impossible to detect when on the ground.
