What If Dinosaurs Never Went Extinct? | Documentary for Sleep

66 million years ago, a rock the size of a mountain hurtled toward Earth... and missed. Tonight, we rewrite history. Join us on a journey through 66 million years of speculative evolution to discover a modern world ruled by dinosaurs, where humans never existed.

The Chicxulub impactor changed the fate of our planet forever. But what if that asteroid had arrived just 10 minutes later? In this documentary, we explore an alternate timeline where the K-Pg extinction event never happened.

We move beyond the movies to answer the scientific questions: How would T-Rex have adapted to the Ice Age? Would Triceratops have evolved into a grassland grazer? And most importantly, would dinosaurs have eventually developed intelligence, civilization, or consciousness?

From the sweltering heat of the Eocene to the frozen tundras of the Pleistocene, we reconstruct the biology, behavior, and evolution of the survivors. We witness the rise of feathered giants, intelligent pack-hunters, and a global ecosystem untouched by human hands.

This is the story of the Earth that might have been.
