Around 100 million years ago , earth was a totally different place , there was no human on the earth , some scary , animals were ruling the planet named as dinosaurs, dinosaurs were very tall , with jaws , that could crush our bones within a second, they were so fast , that they can run with the speed of around 90/km per hour, around 170 million years they ruled the planet , then one day , something happened, that they are vanished from the planet

A large , asteroid, with a diameter of around 10-15 kms , comes towards earth, and crashed into earth, this asteroid speed was 30 km per second, it was hit in yucatan peninsula in Mexico, this is the place , where after millions of years , Mayan tribes emerged, actually when the asteroid hits the earth, one big crater was created, around diameter of 180 km , due to its impact, energy was released so fast , if you compare, it with atomic bombs of Hiroshima, it produced around 1 billions times their energy, this was so big impact, that in a fraction of second, all things near by was destroyed, by this impact lots of soil spreads into the air , and the land got so much heated up , and this hot soil falls on earth, like a hot rain , that the temperature rosed by several degrees for hours , around 1000 of kilometres around this crater all the animals were burnt , only the very small animals survive the impact, because they found underground shelters, or some dive into the waters , then after it heat waves comes , shock waves comes , big sunami came , forests were burned like anything, and dinosaurs got extincted, and a new era begans in the chapter of earth
