It is a popular BELIEF that a meteorite killed the dinosaurs. There is no hard evidence to support it, and as such, your guess is as good as anyone elses.

There are several craters on the planet large enough to support the theory, but the evidence is considerably lacking past that.

Another popular theory is that they simply died out through the process of self extinction. They consumed all available resources, died out slowly, and eventually went extinct.

The existence of a thin layer of meteoric iridium at the K-Pg (Cretaceous-Paleogene) barrier or geologic layers. This is explained by the Alvarez Impact Hypothesis, and supported by the existence of massive craters worldwide from the same epoch.

What are dinosaurs and when did they came to the world?

Dinosaurs are animals that are long before our time. They were extinct 65 million years ago! Though nobody knows when exactly they came into the world, many paleontologists have found remains of dinosaur bones buried under the Earth. There are many theories of how the dinosaurs became extinct...Meteor CrashesVolcanic ExplosionEarthquakesQuicksand, Sinking Mud, TarMoving PlatesGlobal WarmingStarvation (Dying from lack of food)Dry Land/ No Water (Dying from lack of water)Kills (Dinosaurs used to kill each other sometimes)And more...Nobody can really prove the real theory of how the dinosaurs really died, though. They have recovered many Dinosaur Bones and Even some complete skeletons of Dinosaurs! You can see these Dinosaur remains and find out more about Dinosaurs at any Dinosaur Museum!


What is the verb of existence?

well for a true fact, there are many verbs out there that relate to existence. But the main one would have to be living. because of it's extrodinary roatation, in the cycle of existence is life and extinct. but the verb for existence would have to be the opposite verb for extinct. To give you the write answer trust the experts- who wrote this- or prove it for your self. To prove it for your self - work it out- dinosaurs got extint, that had a short life for exisenca, so EXTINCT is your answer!

Did god create Adam and Eve before the dinasaurs?

The bible story of the creation does not explain the evidence for how the world and life formed as discovered by science.Belief in in the existence of God is a matter of faith, not science, science can neither prove or disprove the existence of God.If you believe in God then perhaps the story told by Genesis is more a message about man's relationship with the creator than a real explanation of how the world was made.


Can scientists prove dinosaurs walked the Earth?

Sometimes people say, "Scientists can't prove anything! They can't prove anything they haven't actually observed. So they can't prove dinosaurs walked the Earth!"But is this true? Yes, it's always possible scientists have got something wrong. But of course, that doesn't mean they don't have excellent evidence - good enough that they're justified in feeling sure.After all, in court, people are to prison for committing crimes no one else saw them commit. But if the evidence is strong enough, the judge and jury are still justified in sending the person to jail. We say the person is proved guilty beyong reasonable doubt.Scientists can also prove things beyond reasonable doubt. They can prove beyond reasonable doubt that dinosaurs walked the Earth.
