We all have been told that the dinosaurs became extinct due to a huge asteroid that hit Mexico. Now that theory is seriously challenged by Dr. Unc. He claims that the dinosaurs came to earth inside the asteroid. They were just fine and spread quickly all over the world. They ate anything and everything until there was nothing left to eat. So they started to eat each other, and that’s why they didn’t last long on earth. That was great luck for the humans that came to earth with the next huge asteroid. “We are all such space travelers!” Says Dr. Unc.
