Narrator: Over millions of years, life flourished and diversified, giving rise to the first reptilian ancestors of the dinosaurs. These prehistoric giants dominated the Earth for over 160 million years, evolving into a staggering array of shapes and sizes. However, their reign came to an abrupt end around 65 million years ago, when a catastrophic event, likely an asteroid impact, triggered a mass extinction event. This cataclysmic event spelled the end for the dinosaurs, paving the way for the rise of mammals and eventually, the dawn of humanity.
