Ancient cultures around the world tell stories of strange objects witnessed flying in the sky. But are these tales fiction, or might people living thousands of years ago actually have seen extraterrestrial crafts descending from the heavens?

All over the world there are megalithic stone structures whose construction baffle stonecutters, scientists and archeologists. Is it possible that ancient humans managed to move and cut these gigantic rocks with the help of alien technology?

A 2,000-year-old computer... a power plant inside the Great Pyramid... and a Nazi-era time machine with roots in the ancient history. Throughout the world, there are artifacts and stories that point to advanced technology in the distant past.

Throughout history, there are stories of strange beings unlike anything known to exist on Earth. Could they be more than just mythology?
