Chariots of the Gods

I still recall what a stunning impact this "documentary" had on my family -- including my father, a professor -- when we saw it on television in the early '70's.

Of course, all of von Däniken's assertions have been thoroughly and utterly debunked in the meantime, and von Däniken turned out to be a complete fraud, but still, this was the first time I had ever heard of the Plains of Nazca, so I have to thank Erich for that.

I much prefer the German title to the English: "Erinnerungen an die Zukunft" or "Memories of the Future".
