Asteroid killed them



Scientists have been arguing about how the dinosaurs became extinct.

But today it's official - An asteriod 15km wide slammed into earth and wiped out the magnificent creatures 65 million years ago. (By the way, the earth isn't 6000 years old like some people claim it to be)

A panel of 41 scientists from across the world reviewed 20 years' worth of research and have come to this conclusion.






As of today, there is enough evidence to prove that a huge asteriod slammed into earth about 65 million years ago, sending debris into the atmosphere, blocking out sunlight and creating massive earthquakes.

"We now have great confidence that an asteroid was the cause of the KT extinction. This triggered large-scale fires, earthquakes measuring more than 10 on the Richter scale, and continental landslides, which created tsunamis," said Joanna Morgan of Imperial College London, a co-author of the review.

Because the dinosaurs became extinct, this event allowed the mammals (humans including) to rise up, evolve and eventually to dominate the earth.

The other argument for the extinction was volcanic activity in India that lasted for 1.5 million years. But this argument had many loopholes.

So it's official - Asteroid collision with earth was the cause of the dinosaurs' extinction!

  1. I've always thought that the evidence pointed almost unequivocally towards the impact theory. Thanks for this!
