Solving the biggest mystery of history!
Millions of years ago, giant creatures called Dinosaurs walked on Earth. Some were as tall as buildings. But today, they are all gone. What happened?
Most scientists believe that about 66 million years ago, a giant rock from space (called an asteroid) hit the Earth. It landed in Mexico and caused a huge explosion.
This explosion created a lot of dust and smoke that covered the sun for months. Without sunlight, plants couldn't grow. Without plants, dinosaurs had no food.
Yes, the big dinosaurs are gone forever. We only know about them because we find their "Fossils" (bones turned into stone) buried deep underground.
