How did the dinosaurs die?

One of the main theories about how dinosaurs died is from a meteor. There is no way to prove this, but scientists believe that a meteor could be the only action to wipe out the dinosaur race. It could have created a wave of dust and dirt that covered the Earths atmosphere for many years. With the lack of sunlight (energy) and oxygen (to breath), the dinosaurs and other plants and animals died.

Another is that the water that they drank was poisoned. Poisoned water means no healthy water which means death. There are no ways to prove these theories right, however.

Or methane Gas

Like Flood, The ring of Bubble that give green house effect in the earth making lizard habitable and also plant living longer and bigger.

We need a lot of choice of theory not just one that makes you think this earth really happened randomly

Mathematically it is impossible, but some people say it happened accidently
