Do you know anything about dinosaurs?
Oh, yes, quite a bit. Dinosaurs had lived on the earth for millions of years before humans had ever appeared.
The reason for the disappearence of dinosaurs has been a controversy for a long time, and still has not been solved.
What do you think had happened to the dinosaurs to have made them disappear?
It seems that a large meteorite had exploded on earth about sixty five million years ago.
The meteorite had made a great deal of dust that had risen up into the atmosphere and had blocked the sun's rays.
Which then had stopped vegetation from growing.
This had led to a shortage of food for the dinosaurs, leading to their extinction.
