This show is one of the best documentaries I've seen. It gives us a whole new perspective for looking at archeology and ancient civilizations. The show isn't just a UFO enthusiast or fan made. It's a fully fledged high quality production of History with interviews and location videos from the pyramids of Giza, Egypt. The theory about the Nazca lines and more. I suggest to watch it and gain an alternative theory about our ancient past.
After watching the show I got convinced about this theory more than what the mainstream archaeologist say about their findings. Just keep an open mind when you watch the show.
