Whats the deal with christians and the dinosaurs?

do they believe they existed? and if not, then what are all the fossils and skeletons that are in museums, like actual bones froma once living creature. and like crocodiles have been around for millions of years so were they just hovering around in existance on their own waiting and continuosly breeding like "holy crapgod, come on man,how much longer before we can oy know..... ....have a world to live in." and god was like "ha ha ha millions and millions of years....or maybe tomorow, who knows ha ha ha." how could dinosaurs not have existed when you can clearly see and touch parts of their body in museums.
