Ancient Aliens examines 75 million years of the most credible alien evidence here on Earth, from the age of the dinosaurs, to ancient Egypt, to the skies over the western desert in the present day US.

From the castle of the real Count Dracula to the Super City of Adolf Hitler, history is full of temples, fortresses, lost civilisations and secret worlds left behind by the passage of time.

What would happen if every human being on earth disappeared? This isn't the story of how we might vanish? It is the story of what happens to the world we leave behind. This series explores a world wiped clean of humanity, in even more vivid detail. Just like the special, each episode will use cinematic CGI to reveal - in scientific detail - the fate of every aspect of the man-made world. What happens to the millions of animals that supply our food? The chemicals stored in industrial complexes? Which animals take over subways? Do satellites fall to earth? When does Mt. Rushmore whither away? Every episode will unfold in the hours, days, months and years after people disappear and will combine three to four different kinds of stories, from animal outbreaks to structural collapses, building to a unique visual finale. Life After People, The Series. Welcome to earth, population zero.
