What are the reasons for dinosaurs' disapprearance?

. . . unless . . . some even more complex and highly evolved being with the capability to create life fully formed in all its complexity completely from scratch . . . after simply conjecturing itself into existence . . . erm . . . nevermind.

Sorry Hreeshav.

The problem with creationists is that they were created in god's image, fortunately evolutionists evolved.
All that notwithstanding dinosaurs evolved into birds and remain one of the most successful animal groups on earth. Almost every aspect of bird physiology is more efficient than mammals. The only mammals that fly do so mostly at night to avoid being eaten by .....birds.
