Earth-616

Cretaceous–Paleogene Extinction Event
God, also known as Lord of the Earth, decided that dinosaurs were at a evolutionary dead end and wanted to prepare for the age of mammals. In order to that, he'd caused a sudden mass extinction of some three-quarters of the plant and animal species on Earth, approximately 65 million years ago via an asteroid.
