Dinosaurs are mentioned in the Bible and in ancient literature from many countries. They were called dragons. (The word "dinosaur" was invented in the 1840's, i.e. after most or all of the kinds of dinosaurs/dragons had gone extinct.) There are dragon "legends" remembered in China, Thailand, Vietnam, Germany, Russia, ancient Rome, among the Anglo-Saxons, within several regions of Africa, and even scattered across North and South America. Before humans (and possibly environmental changes) killed them off over the course of thousands of years there is evidence - from around the world! - that humans saw dinosaurs (dragons) out in the wild.
